A plane of Vendrith that manifests only in small portions described as ‘corridors,’ ‘bubbles’ or ‘pocket planes.’ Labyrinthia is entered by performing certain actions while traversing a specific spot in Materia (or possibly other planes), akin to performing a password to open a gate. While it is rare, it is one of the more well established planes on account of the ease of traversing into it once an entrance is discovered. A corridor or gate of Labyrinthia is one which connects to multiple locations in Materia at once, sometimes allowing fast and teleportation-like travel between distant areas. Labyrinthine planes are unstable, however, and may disappear and ‘move’ just as they appeared. Some Labyrinthine pocket planes have lost their gates and become unreachable, possibly forever.
Animals (and especially birds and fish) have been thought to have a sense for Labyrinthine corridors, and are speculated to have spread out and migrated across the world using them.
