I. Introduction
----------------

When you defeat Dalton and obtain the Wings of Time again, the Black Omen
surfaces, like normal. However, two new Gates appear in 65,000,000 B.C. (top
right corner) and 600 A.D. (continent with Ozzie's Fort). For the purpose of
this FAQ, I'll be referring to these areas as Prehistory and the Middle Ages,
respectively.

I didn't start doing these quests until very late in the game, but there's
nothing stopping you from completing them as early as possible - in fact, the
rewards are better the earlier you do this.

There are two basic things you should know about these quests. 1) No items you
find in the Lost Sanctum will have any story effect outside the area and vice
versa. You will not use the Sun Keep or the Sunstone or anything like that. The
only use for SOME of the items in the Lost Sanctum is that they can be used in
battle to restore health (these have no other purpose).

2) When in doubt, talk to every reptite villager. Almost all of these quests
will not be doable until you talk to a specific reptite. If you're stuck or
can't move on according to the guide, go back and talk to the reptites to see
if you accidentally did not start the quest yet.

There are many ways you can use this FAQ. You can follow my basic walkthrough
that covers the specific path I did these in (not necessarily the only path,
for the most part). I also have maps and quick item references at the bottom
of the list that should help you along, should you decide to skip over my
ramblings.

---------------
II. Quest List
---------------

These quests are done in a loose but still fairly linear order. You can veer
from my order as much as you like (in fact, I've had e-mails from numerous
people saying they have done some multi-tasking to alleviate the redundancy of
the dungeon.

Just be prepared to climb up and down the mountain a dozen times. You've been
warned!


----------------------------------
III. Clear the Forest (Prehistory)
----------------------------------

Enter the Prehistory entrance first. The area is empty, so head north into the
forest. Defeat all the enemy groups and collect the treasures along the way
(many of them may seem hidden or out of way, but just touch your way through
the trees and you should be able to pick them up). Return to the first map and
you'll see Reptites, who will thank you. They will offer you quests as well as
hints to complete them.

Reward: Dragon's Tear

----------------------------------
IV. Clear the Forest (Middle Ages)
----------------------------------

You'll be introduced to more reptites, who ask you to empty the north forest of
monsters. Do so and return to the village.

Reward: Megalixir

----------------------------------
V. The Golden Hammer (Prehistory)
----------------------------------

The first reptite on the bottom left of the screen asks you to find the Golden
Hammer. Travel south until you find what looks like a Capsule - and you'll pick
up some Golden Sand. Another Reptite will tell you that you need to drop this
sand on a sprout - do so in the Millenia Wood.

Go to the Middle Ages and when you reach the area where the sapling was before,
you'll encounter a Golden Ogan. Chase him down (found at about the halfway point
in the map) and defeat him to acquire the Golden Hammer. 

BOSS BATTLE

Name: GoldHammer (#234)
HP: 5,800
Defense: 220
Magic Defense: 70
EXP: 2,000
TP: 0
G: 10,000
Treasure: -
Charm: -
Weak: -
Absorbs: -
Immune: -
Location: Lost Sanctum/Millenia Wood (Middle Ages)
Techs: Golden Hammer, Boulder, Thrash
Counters:  Rush

Pretty simple fight. Just keep your guys above 300 HP and you shouldn't have to
worry about his attacks. Rus is a counter that drops HP to 1, so make sure to
have someone on to heal right after.

Return to Prehistory and give the reptite the hammer.

Reward: 100,000 G

---------------------------------
VI. The Prismastone (Prehistory)
---------------------------------

The reptite at the top left of the screen asks you to find a Prismastone to aid
his ailing daughter. He says the stone can be found at the peak of Mount
Emerald, east of the Southern Swamp.

Go south and take a right to enter the mountain area, guarded by a Nu. You
cannot access this area until you take on this quest.

You fight the boss Nu Guardian (dark blue nu with pink hair). 

BOSS BATTLE

Nu Guardian (#235)
HP: 6,100
Defense: 200
Magic Defense: 80
EXP: 2,500
TP: 0
G: 0
Treasure: -
Charm: Mop
Weak: -
Absorbs: -
Immune: -
Location: Lost Sanctum/Mount Emerald base (Prehistory)
Techs: Charge, Head-butt
Counters: Luminaire, Dark Matter, Flare, Ice II, Hypnotize, Time Freeze

Come equipped with some status-null items on, or you'll be in for some trouble.
I noticed he countered more often with the Sleep/Stop spells rather than the
elemental spells. Like the other Nus, his Head-butt attack will drop you to only
1 HP, so keep a healer on. Spamming ultimate magic attacks can kill him in a few
turns.

Defeat him and he moves, promising to train and fight you again.

Make your way to the top and obtain the Prismastone. Climb your way back down
and hand over the stone for your reward.

Reward: Capsule Set (2 Strength, 2 Speed, and 2 Magic Capsules)

----------------------
VI. Prismastone Redux
----------------------

Talk to the reptite below the entrance to the northern forest. It will ask you
to collect another Prismastone and place the two together to create a stronger
item. Place the one you have now in the highest room in the map and go to the
Middle Ages. The elder will ask you to obtain the Reptmark, a rare item in the
northern forest. Bring it to him and he'll allow you entrance into the
sanctuary. Take the Prismastone and return to Prehistory. Place the Prismastone
on the other column and you'll obtain the Saintstone.

Take it to the reptite to get your reward.

Reward: Dragon Arm

-------------------------------
VII. Befriending the Nu Master
-------------------------------

In the Middle Ages after acquiring the first Prismastone, talk to the low left
reptite and he'll mention of a strong creature at the mountainside. Travel
there and you'll find the Nu Guardian, aged and much stronger than before. He
says he'll wait atop the mountain, so start to trek up there once more.

Unfortunately, the way up is blocked due to a broken ladder. Asking a reptite
in the village will inform you that the ladders are made with vines from the
south. Find Sturdy Vines in the Middle Ages. Try and rebuild the bridge and
your party members will decide it's impossible. Take Sturdy Vines to Prehistory
and start your way up the mountainside. You will put a new ladder next to the
one that eventually breaks. Return to the Middle Ages.

Climb to the top of Mount Emerald and you'll fight the Nu Master. 

BOSS BATTLE

Nu Master (#236)
HP: 8,800
Defense: 185
Magic Defense: 70
EXP: 3,800
TP: 0
G: 0
Treasure: -
Charm: Mop
Weak: -
Absorbs: Dark
Immune: -
Location: Lost Sanctum/Mount Emerald peak (Middle Ages)
Techs: Devil's Drop, Thunderbolt, Head-butt, Death's Rainbow, Telekinesis, Over-
drive
Counters: Drain Health

Much tougher than before. His counter attack actually drains a good portion of
health, so watch out. Death's Rainbow is an instant death attack, and for some
reason he used it often against me - Devil's Drop, also dangerous, halves
current HP. Use the same pattern as the other one, just make sure to keep your
healer on the ball.

Defeat him and talk to the petitioner for your reward.

Reward: Nova Armor

----------------------------------------
VIII. Building the Bridge (Middle Ages)
----------------------------------------

The reptite below the entrance to the Millenia Wood desires to build a bridge
for you. To do so, he requires metal, a durable hammer and sturdy lumber.

The Steel Ingot is in the cave to the west of the swamp in the Middle Ages.

The Golden Hammer can be retrieved from the same reptite you gave it to in
Prehistory.

You can obtain Godwood from the reptite at the entrance to the Millenia Forest
in Prehistory. Talk to the lower right reptite first if he doesn't hand it
over.

Bring them back to the reptite in the Middle Ages and he'll go to the mountains
to build his bridge.

Reward: Haste Helm

-------------------------------------------------------------------------------
IX. Finding the Bridge Builder (Middle Ages)
-------------------------------------------------------------------------------

The neighbor of the bridge builder is concerned when his friend doesn't return
home. He asks you check on him. Climb up the mountain and wake the Nu Master.
Ask for his aid and he'll move out of the way for you. Follow the path until
you come across the bridge builder dangling from his bridge. Go back to the Nu
and have him help build the bridge.

Go back to the village and get a Hearty Lunch to take back up. The Nu is fed
and asks you to get some more food. This time you need to go back to Prehistory
and talk to the villagers. They suggest you kill some enemies to find food. He
asked for something yellow, so fight until you find a Sweet Banana (found after
defeating a purple blob monster and two frogs, found in a dead end in the
Southern Swamp.)

Note: There are other food items that you can get, but as far as I know (and the
treasure guide in the game, too), there's no reward for getting them. They will
net you healing items to use in battle, and only waste your time climbing up
and down the mountain. The Sweet Banana is the only fruit that will finish this
quest.

Hike back up the mountain in the Middle Ages to give the Nu the Sweet Banana.
He will finish building the bridge after a while. 

Come back here after completing the Dark Cavern mission and the Nu is done.
You return to the village where the Nu finally makes friends and opens a shop.

Reward: Saurian Leathers

--------------------------------
X. The Dark Cavern (Prehistory)
--------------------------------

Take the Saintstone (see Prismastone Redux) and place it atop Mount Emerald in
Prehistory. Return to the top in the Middle Ages and pick up the new Waystone.
Go back to Prehistory and talk to the reptite at the bottom right. Agree to
explore the cave and be on your way.

The light fills up the room and allows you to continue on. Move forward and
your party members will hide as Twin Snake enemies make their way in. Overhear
their plans and they will then notice you. Your party members decide to warn
the villagers of the monsters - only to hear screams from further in the cave.

Return to the village (automatically) and warn the villagers of the impending
attack. They hold a meeting and you promise to defeat the monsters planning to
invade their village.

Reward: Judgment Scythe

------------------------------------
XI. Defend the Village (Prehistory)
------------------------------------

The reptites ask you to return to the dark cave, so do so. While you head down
there you run into gold Chryosaurs, seemingly on their way to the village. You
fight them and continue on towards the castle. When you get further down in the
castle, you're met with a crossroads. Going left will let you pick up a new
weapon for Lucca, and you'll be deposited back at the crossroads. 

Both staircases lead to the same room. The left door will net you a Megalixir
and a Dragon Armor. The right door gives you some really weak treasures. Go in
the center door and take a left to get a Stardust Bow. Go back to the right and
continue around outside. Go up a few flight of stairs and you'll pick up a
Reptite Dress. Go back one flight and go down the center door. Save your game
and you'll meet the bosses, a red and blue set of fat gargoyle creatures from
the Black Omen, called Archaeofangs. 

BOSS BATTLE

Archaeofang (Elder)
HP: 8,000
Defense: 150
Magic Defense: 60
EXP: 3100
TP: 0
G: 0
Treasure: -
Charm: -
Weak: Ice/Water
Absorbs: Fire
Immune: -
Location: Lost Sanctum/Castle (Prehistory)
Techs: Twin Attack, Earthshaker, Flare, Volcano, Dark Matter, Soul Link
Counters: Osmose

Archaeofang (Younger)
HP: 7,500
Defense: 160
Magic Defense: 55
EXP: 3100
TP: 0
G: 0
Treasure: -
Charm: -
Weak: Fire
Absorbs: Ice/Water
Immune: -
Location: Lost Sanctum/Castle (Prehistory)
Techs: Twin Attack, Earthshaker, Water Surge, Water II, Snowstorm, Dark Matter,
Soul Link
Counters: Osmose

These guys are pains. Basically, everything you do results in a Counter-Osmose.
This will obviously drain your MP, and physical attacks aren't nearly as strong
as combo/magic attacks. Most of its attacks are just higher-tiered elemental
attacks you've seen from other enemies - so boost up magic defense and use
barriers to lessen the damage.

You have to kill the two of them together, or at least a round apart. If you
don't, the one will revive the other (fully!) and you'll be at a loss. My time-
consuming strategy was this. Spam Luminaire/Electrocute/etc. that damages the
both of them. One should fall before the other, and LET him revive the other.
Then damage the one that was just revived until it dies - the remaining enemy
should have little HP and die within a few hits. If this doesn't work in time,
repeat and you're guaranteed the win.

Other users have suggested using opposite elements (not fire/ice) with two of
your characters and that will roughly even out the damage to both enemies. You
can also bring Ayla and Crono along to use their combo Falcon Strike to deal
about even damage to the both of them. Antipode (and its upgraged forms) are
also great damage dealers.

Finish the battle and you'll return to the village.

Reward: Valor Crest

-----------------------------------------
XII. Tower of the Ancients (Middle Ages)
-----------------------------------------

The elder will ask you to investigate the tower across the newly built bridge.
Head back up Mount Emerald againand fight your way across the bridge. The map
is pretty straightforward, so just follow along until the map extends slightly
to the right. Pick up the treasure for a Rusted Blade, something you can use
later.

Reach the top and you'll fight two undead knights.

BOSS BATTLE

Master-at-Arms (#239)
HP: 14,500
Defense: 160
Magic Defense: 80
EXP: 7,000
TP: 0
G: 0
Treasure: -
Charm: -
Weak: -
Absorbs: -
Immune: Light
Location: Lost Sanctum/Tower of the Ancients (Middle Ages)
Techs: Holy Light, Thunder, Whirlwind
Counters: Tsubame Gaeshi, Flash of Steel

Bladesman (#240)
HP: 9,000
Defense: 100
Magic Defense: 50
EXP: 1,200
TP: 0
G: 0
Treasure: -
Charm: -
Weak: -
Absorbs: Dark
Immune: -
Location: Lost Sanctum/Tower of the Ancients (Middle Ages)
Techs: Sword Strike, Blade Dance, Desperate Strike, First Aid
Counters: -

Kill the little guy first. He doesn't counter and has a bad habit of healing
the Master-at-Arms. His attacks are purely physical, too.

The big guy is the one you need to worry about. He counters everything, most
commonly with the Tsubame Gaeshi, a decent physical attack. His magic attacks
can do decent damage, but just keep up healing and you should be fine. I
considered the Archaeofangs much tougher bosses.

After the battle go through the door to find...

...statues of yourselves. Yes, you are the idols that protect the reptite
village. You automatically return to the village where the reptites greet you.

Reward: Champion's Badge


-----------------------
XIV. Lumicite and You
-----------------------

You may chance across an enemy unit that is a palette swap of the Rubble
enemies in your run through of the various dungeons. He is a tricky foe
with high speed/evasion and will run at a moments notice. He also has a
bad habit of appearing randomly through the dungeon - some players have
searched for hours to find him.

The search is worth the effort, however, as he drops (and can be stolen
of) the rare Lumicite, which lets you trade it with a reptite (600 A.D.)
What you get in return is arguably one of the best pieces of armor in the
game - for Lucca. It has elemental properties that make it very useful, and
if you use the kooky scientist you would be a fool not
to take the time to find it.

---------------------
XV. Item Reference
---------------------

Use this as a quick reference of location/era, if you don't want the entire
quest spoiled for you.

Item - Location - Era

Dried Mushroom* - Mount Emerald - Prehistory
Godwood - Millenia Forest - Prehistory
Golden Hammer - Millenia Forest - Middle Ages
Golden Hammer (2) - Reptite Village - Prehistory
Hearty Lunch - Reptite Village - Middle Ages
Millenia Fruit* - Millenia Forest - Prehistory
Prismastone - Mount Emerald - Prehistory
Prismastone (2) - Village - Middle Ages
Reptmark - Millenia Forest - Middle Ages
Saintstone - Village - Prehistory
Songbird Egg* - Mount Emerald - Prehistory
Smoked Meat* - Winding Cave - Prehistory
Steel Ingot - Winding Cave - Middle Ages
Sturdy Vines - Southern Glade - Middle Ages
Sweet Banana - Southern Glade - Prehistory
Waystone - Mount Emerald - Middle Ages
Lumicite - Anywhere - Prehistory/Middle Ages

* - all items found searching for the Sweet Banana, but they will not complete
this part of the quest (ie, they're useless outside of battle)

-------------------
XVI. Map Reference
-------------------

The following maps have been created by me to go over the treasure data as well
as give basic guidelines as to where you can find key items and such. The
important thing to remember is that many key items will not be available to
you until you accept or complete the corresponding quest. So don't make a topic
complaining about not being able to find the Sweet Banana when you don't even
need it yet.
