A powerful spirit, elevated by a dark entity to a position of power. Demon-Lords of a given kind are members of orders, each order having been created together long ago. Most serve Mwt, who has maintained dominion over the more well known tracts of hell for several millennia.
Demon-Lord's may be summoned in secret by mages for nefarious purposes. They may be used as guards, but more frequently are used to direct hordes of lesser hellions/fiends.
In the bureaucracy of Mwt's Hell, demon-lords do not answer directly to Mwt, but are under the thumb of unique Hellions, sometimes called Archdemons, who are frequently lesser deities, or demigods made to submit to Mwt.
