So I found the Library when I became King and it has 4 statues in each corner that talk about the 3 greatest heros leaving behind 3 talismans. I assume once you have these then you get to go behind that locked door in the same room but I'm not sure what I should be finding or what I should do when I find them! I'm level 5 in all areas (Strength, Stature, Magic, plus all chests opened on the RtR). As I'm typing this I'm wondering if I have to bring the 3 default weapons given to me in the begining. Is that correct and if so do I just talk to that final statue?
You have to talk to the statues in the correct order, which you can figure out from the story they tell. You don't need to bring anything. I don't even think the talismans are in the game. And all that's behind the door is a chest, but I can't remember what was in it.
If you love someone, set them free. If they return, put several six-inch blades into their head. If they still return, run. Just...just run.
