Embers in the shadows

Appearing from the earth, a tower that reached the stars was able to shake humanity’s core. Choosing people from the outside to act as slayers that defend humanity from monsters and demons. 2000 years after its appearance the tower chose Finn Hutton as a slayer. Unexpectedly so, the tower was resented for its choice. The brother of Finn, Alan Hutton was outraged and cursed the the tower. Calling upon the tower for an answer. Alan in return receives a contract that would sacrifice his body and give him the opportunity to save his brother. But what Alan wasn’t aware of was that he would not have a body for him to inhabit. Forced into the body of a goblin, Alan is now stuck as a parasite. All he can do now is watching from the sidelines as he tries to take control of his host and save his brother from certain doom.
