Onyx Tile World

The Onyx Tile World is one of the main areas accessible from the Nexus, through the green screw-like object.

Features
Onyx Tile World is a vast, narrow, and dim world made out of marbled onyx tiles, as the name suggests. It has a labyrinth layout, filled with purple tube-like objects with green interiors and populated by tentacles coming out of the ground, whose colors are determined by how many dream sessions have been done, as well as numerous Shadow Gloops and a Shadow Bird lurking the area, trapping Urotsuki in an isolated area when caught.

There is a grayscale pencil that leads to Character World C which you can find by heading north of the entrance, then taking the eastern path past the Shadow Gloops, and then going northeast from said path.

Directions
Nexus → Onyx Tile World
