The Ancient Crypt (古代遺跡, Godai Iseki, Ancient Ruins)is a small area accessible from the Crimson Labyrinth.
Features
The Ancient Crypt is a maze-like area, carved out of stones of odd and varied colors. It acts as a bit of a maze, similar to areas such as the FC Dungeon and the last section of Monochrome GB World, where travel between the various areas is facilitated by staircases that lead up and down.
Immediately from the entrance, it is possible to head south and weave through the tunnels to arrive at an NPC that appears to resemble an Unown with four jellyfish-like tails, which will teleport the player to the Deserted Pier. This is the only part of the area where the path branches; taking the other path will have the player weave through a different, and much longer, set of tunnels.
Halfway through the area, the colors will change, increasing in saturation. at this point, the player can head north to find a brown barrel sitting at the end of a corridor, which when interacted with will show an image of an abstract being with many faces, flashing in many colors. After here, travel to the end of the area continues to be linear, and eventually ends in a portal to the Radiant Stones Pathway.
