Undead Horde V1.1.2 €? GOG

A demon lord is a very powerful and unique demon. They are by definition rulers of at least one layer of the Abyss, and have hordes of nascent demon lords and lesser demons in their service. Being creatures of chaos, however, not all demons are servants to a demon lord.[1] As the Abyss is nigh infinite, so too are the number of demon lords.[2]
