Rebirth (Danny Phantom and Rise of the Guardians crossover)

BEFORE YOU START I wasn't you all to know that I don't update that fast, so I apologize in advance for any gaps

What happens when Danny Phantom... Dies? Will he become a ghost? Maybe not, but then would he move on? And what do the guardians have to do with this? (There will be some Badger Cereal jsyk XD)
