Occult Biome

The Occult Biome is best representative of realms like Hell or Graveyards filled with zombies or doom lord castles or even dream/mindscapes. The air is charged with magical energies - mostly of the sinister variety. 

Known Sub-Biomes

 * Cathedral
 * Graveyard
 * Dungeon
 * Ruins
 * Hades
 * Enigma - since this name is rather vague, it bears explanation. The Enigma Sub-Biome is a space that defies physics. This is a location where people can enter the minds and dreams of others as well as things like Escher's Hell, giant toy boxes, etc. The space within the Enigma Sub-Biome is said to be infinitely expansive. Once entering, it is unclear whether or not one can escape the way they came.

Known Landmarks

 * Wizard's Castle - one of the easily spotted sights in the Ruins Sub-biome, this castle suddenly manifested one day - and it is said an Administrator dwells in the inner sanctums of this locale. Those who leave triumphant generally do not speak of their interactions with this administrator.
 * Labyrinth - also within the ruins is a door that leads into a maze only known as the Labyrinth. The administrator of the Labyrinth, the Erinyes Vera von Avarideus, is known for booby-trapping the journey to the Labyrinth and the Labyrinth itself with all sorts of hazards. Of the many administrators, she is one of the less forgiving ones.
 * (unnamed) Undead Village - The population consists of sentient undead and a monstrous humanoids. Sometimes this settlement must contend with would-be heroes who do not quite get the concept of "don't be a prejudiced asshole." This has made this little undead hamlet quite wary of foreigners.

Known Races

 * Sentient Undead - some undead manage to regain something of their humanity - some manage retain all of it. Cursed with deprivation of the eternal sleep, or perhaps made to wander for a bit longer until they find something they desired in a past life, sentient undead tend to band together in settlements for fear of those who are still of the mortal coil. Oftentimes, even if mortals visit, they quickly leave out of feeling quite the chilly reception from the surrounding doom and gloom atmosphere. Notable sentient undead include vampires, liches, ghosts, and skeletons. Occasionally a zombie becomes sentient as well, but oftentimes they find themselves quite mentally impaired.

Ridia

 * Effigy - Effigies are spirits that are attracted by and feed upon emotions. Their arrival is generally marked by a certain "void" in one's emotions - as if suffering from a severe sudden depressive episode. Prolonged exposure leads to an individual becoming a temporary host for an Effigy.
