A realm, intersected with the human plane, is inhabited with 'shadows'. Victims are considered hosts of parasites- the shadow demon. Fortunately, most shadows are weak and prefer the casual stalking of their host.

Catheris Orial, a 26 year old designer - gets incidentally roped into the convergence between the human and shadow realm by his own 'delusions'.

However, he does have quite the involvement with his family history, which extends back to a small island off Virosiad, the mainland, located in the middle of the sea. Where his ancestral roots originate from - Deliamois, known for its mysterious setting.

Something is wrong, the dreams he's been having get more and more obscure in their nature. After a few dream-occurrences transpire in Catheris's basic, boring life, he realizes that the dreams' contents may be slipping into reality.

There's a certain 'thing' with its prying eyes on him, and him only.

In conclusion, the man is fucked, literally and metaphorically.
