Overlays

An overlay is a rare type of entity which displays imagery that is fixed to your peripheral vision, much like a logo in the corner of a tv channel.

Behavior
The intent of this entity is unknown, often seeming entirely pointless. It isn't quite a Mare, but, in some extreme cases, can try to scare you by flashing frightening images over your vision. The imagery has the ability to move and even communicate. It sometimes activates in order to suit the mood of a situation, or assist another entity.
