Into the Unknown

Tumblr Prompt: End of season two divergence: as Lucifer is about to throw the sword away, he stops to think a little and decides to instead keep it to prevent his father from forcing him back to hell (and also to visit his mother from time to time -not that he will ever admit it, even to himself). Fast-forward to season 4 right when Eve comes while Lucifer is at his lowest point with Chloe, and, remembering the sword (he may or may not have used it to solve Cain's death problem), he impulsively invites her and Maze (maybe Amenadiel, Linda and Charlie, too? they could realistically accept for Charlie's sake if you time it right while upping their worry about angels kidnapping Charlie) to travel to another universe outside his father's authority. From there it could be either his mother's creation or any other. I would personally like if it were an universe with its own Lucifer and if this Lucifer was onboard the "Apocalypse Now!" Train (from the top of my head: Supernatural, Good Omens, the Omen, American Horror Story: Apocalypse) would be specially fun to see our favorite Lucifer interacting with his counterpart's child if they had.
