Anti-Necromancer: Hell Tree
A very strange being has apparently done something very wrong. To pay for his misdeed(s), he's dispatched on dangerous errands, by some sort of higher powers.
It's Halloween night and the being is ordered to stay the night in a mangrove swamp, along the coast of Florida.
The being is not alone, he's accompanied by a demon, named Glyr.
Glyr has the form of a short sword.
