Long ago, the greatest minds in Entirety decided to create two schools - Hell and Heaven College - to provide education and training to beings of all species and dispositions. Hell College - ruled over by the mighty Underkings - was oriented toward demons, monsters, and other species often ostracized for their appearances and mannerisms. At Hell College they could learn how to manage their lifestyles, develop their abilities, and shoot for the top by displaying their power and wits.
Hell and Heaven College once got along well, but in recent years Heaven College has developed a powerful hatred for Hell College and all of demonkind. Relationships between the two are tense, leaving Hell College struggling to decide if they should respond in kind or figure out how to repair relations...
Among some of the most powerful beings in Entirety are the Underkings: the overseers of Hell College and examplars of their sin. Their personalities and opinions on the nature of demonhood vary wildly, but all of them are formidable foes who are rightfully feared.
