The Community Event is a game-wide server side tracking of how much magic is put into each pool: Light or Dark.

When enough Magic is put into one side that side is unlocked. If you contributed to that pool you will get rewards consumate with the amount of magic you put in yourself.

That's how I've interpreted it, at least.
