Terrigena

One of the six realms of Eidolon.

Most Ghouls think this realm is just fire and brimstone, and often call it "Hell" or the "Underworld".
The land of Terrigena is a near-desolate, volcanic environment, and the oppressive nature of the Dragon's Eye prevents Ghouls with lesser magic from even setting foot in this realm. In a showcase of their might and power, the Draghouls decided to settle here long ago. It's always warm and dry, with no need to worry about even the slightest hint of cold, frigid winters. Many Ghouls who have settled in Terrigena take occupations that involve magic or mining.
