Hidebehind

The Hidebehind is a nocturnal, forest-dwelling spectre that preys on human-like creatures. It can shift its shape, allowing it to hide behind almost any object.

History
In the early 1620s, a Hidebehind of unusual size and strength was chased away by Isolt Sayre after it had managed to capture a young Pukwudgie. The same hidebehind was later responsible for the deaths of the parents of Chadwick and Webster Boot.
