Ysval

Ysval is a nighthaunt; a sentient undead being from the Plane of Shadow - an avatar of darkness.

Appearance
Ysval somewhat resembles a gargoyle with bat wings, talons, curling horns and a whipping serpentine tail. His body looks as if made of the shadow-stuff of the night itself. His has no face, just a flat triangular space set with a pair of pale eyes blank and round as pearls.

Abilities
Unlike many other undead creatures, Ysval can bear the touch of sunlight without actual harm, though it makes him feel uncomfortable. He has the mystical strength to darken the day to a point where it seems almost as dark as during the night. When conversing with his underlings, Ysval uses a psychic bond for communication without words.

History
In 1375 DR, Ysval leads an army of undead to conquer Thay. He feels kindred spirit with Shex, one of his commanders.
