The map was pulled from all public hosts in 2010 after a player claimed that, after spending four consecutive hours in ylym_forest_b3 , his real-world apartment began exhibiting the geometry drift: his hallway elongated, his bedroom window faced a forest that had never been there, and his reflection no longer followed his movements perfectly.
Entering Ylym requires a specific kind of courage: not the courage of the hero who charges the dragon, but the courage of the cartographer who admits the map is wrong. Most people never enter. They build villages at the edge, light bonfires, and invent gods to explain the rustling in the dark. They call this "civilization." ---- Ylym Dark Forest
