Wisp

Wisps are creatures from Allyra. They are altogether evil and can only be killed by a wound from a weapon and the words of Ellos. The words of Ellos at anytime cause them to shudder like they have a violent cold. They normally appear as smoky clouds that can take shape, but they can take the appearance of any person. Therefore, they make perfect spies and assasins.

The Wisp which took on the shape of Mr. Wallace began to shake and turn into smoke until a dead Gwar fell on it. It absorbed and devoured the Gwar, and then took on a more stable form. This hints that Wisps need to have eaten reccently to take the shape of another person.

Appearances
The Wisps were one of the first stages of the surprise attack on Berinfell. They slipped into the city, killed guards and took their shape to surprise and confuse the Elves. Two Wisps killed Kiri Lee Yuen's parents and attempted to kill her though she managed to escape using her newly-found power. A Wisp killed Jimmy Gresham's neighbor, though failed to kill Jimmy himself before Jimmy's teacher killed it. A Wisp killed Mr. Wallace during the Battle of Dolhousie Castle and used his shape to infiltrate Nightwash Caverns. It is implied that the same Wisp took the shape of Kiri Lee during the Attack on Vesper Craig.
