Harry Potter and the rise of the shadow crystal

when a dangerous crystal crashes on earth, it means that the apocalypse is near, harry and his friends must face against this sadistic enemy. 
the villain: the antagonist is not a alien, it's a evil living crystal that wants to rule earth and make it as his own "planet".
to make things more awesome, it's gonna be a crossover with different franchises (whenever you like or not).
I don't know what to add next, but if you have a suggestion, let me know in comments!
