Changelings

Changelings come in many types; from lesser tricksters in the Black Forest, to entities inhibiting human bodies in service to the MW, to Entities with a Threat Level of "extinctor". They reason they are grouped together is that they all have a common feature: their main form is of a humanoid and can easily pass for a human. Changelings also have a sort of aura around them that makes human beings uneasy.
