Horrors Unbound: Black Orc (5e)
Followers of Orcus¸ Demon Prince of the Undead¸ black orcs (Orco pulleiaceus) are larger and more barbarous than their cousins¸ the common orc. Believing themselves to be the favored of Orcus¸ they wage self-righteous wars of conquest on all their neighbors¸ be they goodly races¸ other evil humanoids¸ or even other clans of black orcs. Constant intra-clan warring usually keeps their numbers in check¸ much to the relief of neighboring civilizations. However¸ when a clan is led by a black orc high priest or priestess¸ who is almost always accompanied by one or more black
orc champions¸ the clan becomes focused and organized¸ often forcefully welcoming other clans into its fold to create a powerful army capable of threatening the most welldefended kingdoms.
