Nightmare

Nightmares, also called Dreadsteeds, are beastial, Horse-like Demons in service to the Burning Legion. Native to the Legion world of Xoroth, Dreadsteeds have been used by the Nathrezim race as a means of transportation for centuries. Dread steeds are exceptionally unruly Demons, and are capable of causing great destruction if left to their own ends. While non-sapient, Dreadsteeds display intelligence of disturbing cunning, and underestimating one is a dangerous move.

Warlocks have learned how to summon Dreadsteeds to serve as Mounts. Unlike the lesser Demons of the Legion, these Demonic steeds refuse to make pacts with Warlocks, and their Nathrezim masters guard them well. To acquire one, a Dreadsteed must be stolen from Xoroth and subjugated to the will of the Warlock, making Nightmares prized mounts among Demonologists.
