World of Lyocra (Massive Crossover RP)

[Coincidental Madness]

The background of this roleplay so far:

There are many undiscovered lands that are out there, left as a mystery unknown. One world calls out and brings foreign people from other lands to it, the world called Lyocra. Why? No one exactly knows, but a voice that speaks out from nowhere announces to the displaced foreigners of a treasure that sleeps somewhere hidden in Lyocra. A treasure of one single limitless wish. Who will receive the treasure first and obtain a wish for the better or for themselves? It's up to them to write this story's pages...

That's all I had in mind for now, I'll probably do some minor changes later on. This is just the idea right now. This is going to be a free-roam massive crossover roleplay, the treasure is everyone's goal. I'll accept canon characters and original characters, but they have to come from a fandom at least. Just looking for interest and some suggestions.
