Magic Within

Bill Cipher is hellbent on finding his long lost son. He learns the axolotl has placed his child in another dimension where neither of them have jurisdiction to set world rules. He immediately leaves to find him after his "defeat" from the pines twins, but what happens when he finds out the truth? Will he try to destroy the world that has taken his son or will he join it and start over?

(Based on a popular yet debunked fan theory. It's only labeled a crossover because of one character coming into the main world that's being focused on. Lots of OOC in this fic too. Editing comes later, for now I'm just going to write the story.)
