So, this prompt I got off Tumblr, and I thought it looked cool, so why not?

The Prompt
You own a hotel where fictional characters arrive from their respective universes for a break from the havoc of the worlds their authors create for them. Generally, things are quite peaceful, considering you've set up a strict rulebook & have the power to back it up yourself. Today, you can't help but tell a few guests are using the hotel as a front for breaking one of the most carefully-upheld rules: never exchange materials & items from other fictional domains.

The Adaption
Someone co-owns a hotel (With Deadpool) where *fictional* characters arrive from their respective universes for downtime from the havoc of wherever the author of their stories set them down. Usually, it's pretty peaceful. The hotel has a strict rulebook and the person has the power to back up these rules. One of the most important rules is to NEVER exchange materials/items from other fictional domains. There is suspicion that this rule is being broken.

What this Means
The protagonist owns a hotel (Hotel Fantasia). Deadpool, because he is most notable for breaking the fourth wall, is co-owner alongside said protagonist. The hotel is basically a Stonehenge into the different fandom worlds. This will include fanfic if I deem it good enough. The protagonist has a strict rulebook enforced by their power to back it up. When the stories are getting messed up with items from other fandoms,  the protagonist turns to inside their walls to find the threat.

SO, this story is basically a multi-fandom story. Probs focused on Marvel, Percy Jackson, Warriors, Summoner and Wings of Fire as I am small, uneducated and too busy to be adding fifteen different things in.
