Description
An aeon phage exists to protect the living by eliminating resurrected beings, they will accomplish this by any means necessary even if that means ending the lives of those they seemingly protect.
An aeon phage is a hunched slender figure with long arms and two secondary appendages, they are a large creature with pale skin and a triangular face with four empty sockets in place of eyes, they have an ability to move through walls and objects, not even extra planar travellers are safe as the aeon phage can move through dimensions in search of their prey.
