Wreys are feys reflecting the merciless, predator side of nature. They seek to protect nature, but they also want to punish who harms it. They do so by excessive force and violence. They know no mercy and they want to eliminate their enemies quickly. They can easily perceive a woodcutter with an axe or a torch-bearing knight as a threat.
Corrupted Fey. Although wreys were peaceful and good creatures once, their characteristics totally changed when they encountered a mind-affecting shadow. They were twisted by the shadow and filled with emptiness. When they came back to their forest, they saw woodcutters chopping down trees. At this moment, the emptiness within them is filled with rage and it has not been eased since then.
Some speculate that the shadow was an intelligent being, some others say that it was the job of an evil necromancer. On the other hand, according to others, it was a branch of Shadowfell influence and even some claims that the shadow was created by the fiends.
Wreys generally eat their victims and decorate their homes with the victims’ bones.
