NIGHTMARE
A nightmare appears in a cloud of roiling smoke, its
mane, tail, and hooves wreathed in flame. The creature's
unearthly black form moves with supernatural speed,
vanishing in a cloud of brimstone as quickly as
it appeared.
Dread Steed. Also called a "demon horse" or "hell
horse," the nightmare serves as a steed for creatures of
exceptional evil, carrying demons, devils, death knights,
liches, night hags, and other vile monsters. It resembles
a fie ndish horse, and a nightmare's fiery red eyes betray
its malevole nt intelligence.
A nightmare can be summoned from the Lower
Planes, but unless a worthy sacrifice is offered to it as
food upon its arrival, the nightmare displays no special
loyalty to the creature it serves.
Creating a Nightmare. Nightmares don't appear
naturally in the multiverse. They must be created from
pegasi. The ritual that creates a nightmare requires the
torturous removal of a pegasus's wings, driving that
noble creature to evil as it is transformed by dark magic.
