SPECIAL ABILITIES

Smoke Aura (Su)

15 feet. The nightmare continually exhales black smoke that creates concealment in an area around it. Nightmares and their riders can see through this smoke. A creature that begins its turn in the area becomes sickened (DC 14 Fortitude negates) for 1 minute. The nightmare, its rider, any creature currently holding its breath (or that does not need to breathe), and any creature immune to poison are immune to the aura’s sickened effect but not the concealment.

ECOLOGY

Environment any (any evil plane)
Organization solitary

Nightmares are evil creatures that appear to be black horses with fiery eyes and hooves. They are a type of fiend that exists in the dimensions beyond the Material Plane. There, they serve as steeds to powerful evil beings such as hags and demon princes. One should be careful to think a nightmare to be a stupid beast; they are as intelligent as a human, but also wicked and depraved.

Nightmares are often conjured into the world to serve as steeds for evil priests and wizards. Sometimes they are sent to a mortal as a “reward” for service to a powerful fiendish lord.
