Nightshades

are large undead creatures from the Plane of Shadow. They are a horrifying mixture of death and darkness, made more frightening by their alien intelligence and spellcasting powers. All nightshades were surrounded by an aura of desecration that could draw life from the living. Their powers were considerably enhanced in darkness, but they were also greatly weakened by natural sunlight. Nightshades communicated telepathically.

Known Nightshades
Nightcrawler: are enormous black worms, similar in size and strength to a purple worm. Despite their shape, they were deviously intelligent and accomplished spellcasters.

Nighthaunt: resembling giant gargoyles, nighthaunts had strategic minds and were known to lead armies of undead. Nighthaunts are surrounded by aura of desecration, can drain levels with a touch, and are powerful spellcasters. However, they become weak in natural daylight.

Nightwalker: taller than a building, nightwalkers were nightmarish giants yet also excellent stalkers. A nightwalker's body looked as if it was made of shadow-stuff, with a vaguely humanoid form. They were about the size of a house, but were usually no taller than 20 ft. (6.1 m), and their bodies were smooth and hairless. Nightwalkers were the shades of extremely strong-willed and evil mortals whose ancient and unyielding will and malice allowed them to hold their corporeal shape.

Nightwing: resembled an enormous bat made of darkness. Virtually invisible, they could drain magic from an enchanted item.
