Mari-Morgen
A ghost/water spirit of welsch myth, a creature made of the spirits of the drowned.
These spirits are not necessarily malicious in nature, instead serving as guardians of the sea, drowning those who would dare harm sea life or threaten the balance of nature.
As spirits, their spiritual body is made of ectoplasma, however this energy expresses itself more uniquely as a viscous fluid. Their fluid body allows them to not only blend into, but literally become the sea.
