There is a shrine just to the west of the floodgate that you enter to unlock it. --- "And if you don't believe the sun will rise, stand alone and greet the coming night, in the last remaining light."-Audioslave
It's NW from Sorceria right? Not NE like the guide says and also how do you access it? I just beat Gracos and got access to Sorceria but when I approach that gate it says there is no key hole on this side and won't open. So how do I access Slimopolis?.
