The entire lower 35% or so of the planet is an empty, hostile wasteland. Reports from some particularly resilient warriors state that dead bodies have been found underground here, suggesting that some creatures, a secret society, or something else uses the area as a great graveyard. The contents of the atmosphere around this area aren't entirely consistent, but it can be safely assumed that most of it is composed of very little oxygen, almost no Mist, and a great mass of Miasma. According to reports, the monsters are worse than the air. Anyone who's less than Lv4 can expect to survive for less than a minute.
