Editing Adventure Time (section)

==Short history==
The seminal moment that would lay the groundwork for virtually all subsequent events in the AT universe occurs in the frigging Cretaceous Era of Earth when a Catalyst Comet is detected heading towards the planet. The comets always bring forth some (agent of) change which the current inhabitants usually don't want or fear so an artifact - the Ice Crown is created in order to stop the impact. It fails and the planet goes through a transition. Fast forward to the 21st century and humanity nukes itself for unspecified reasons with one bomb falling onto the original comet that bore a being of pure evil - The Lich. This war either wipes out all life or mutates it into precursors of later beings that inhabit Ooo, helped along with the return of magic. About 1000 years later the series proper starts and takes place mostly over a period covering 5ish years. After that the future is not so thoroughly explored (though a spin-off, epilogue of sorts is there too)  a further 1000 years into the future (about ~4000 AD/CE) we glimpse the land of Ooo develop into an even more advanced state than the 21st century humanity was with implications that it will fall just as the prior did (though again not without leaving it's own offspring).
