Summoning Shenanigans

Adding in[participant in the Royal Road Writathon challenge] Sean was a chemist on Earth with a lovely family life.  Everything was going well, until a group of gods decide to summon him to their world.  An unfortunate appearance by the trickster god derailed a normal summoning, and now Sean finds himself in a pickle. Content warning:  There will be profanity and quite probably some gore, though the point of the story will not revovle around any gory scenes.  I'm also including traumatising content as there will for sure be slavery and rape.  The rape will be alluded to and not described, there are other places for that.  I think this also explains the grimdark tag.
