Humans were once gods but our divinity has been sealed. However, the seal is leaking, combining with our focus on numerous fictions to create countless demi-planes based on fictional worlds. This has destabilized the space around Earth creating rifts leading to these worlds.
Javier Jaun Cortez gets sucked into the first rift to open up and isekai'ed. His body is disassembled and reassembled on the other side in the process, breaking the seal on his divinity. Join him on his journey through countless worlds, he will conquer, he will save and he will return.
P.S. I was posting on here so that people can't steal my story and post it here. However, turns out Reddit has an infinite license to anything you post on there, and a lot of people are stealing Reddit novels to post elsewhere. So I will be continuing to post on scribble-hub instead of Reddit.
