The Great Vortex is a portal at the center of Ulthuan through which chaotic magic is gathered and flushed out of the material world and back into the Realm of Chaos. It is a very important thing to anyone in the Warhammer Fantasy world who does not want chaos to overrun the world.
It was created by Caledor Dragontamer and a cabal of the most powerful elven mages of the age in order to drain the winds of magic to starve the daemon hordes rampaging across the Warhammer World. This worked like a treat although Caledor and his mages were stuck forever in a ghostly existence maintaining the whirlpool and much of Ulthuan was damaged by the spell.
This spell keeps the world free of the worst of chaos, which makes you beg the question why anyone would be insane enough to try to disturb it. Well, in a fit of genius (read madness) Malekith and his skanney mother and their dark elf cronies tried to do just that, believing the hordes of chaos would rush to their aid when they were losing the original elf civil war. Thankfully Caledor was having none of them and bitchslapped Malekith so hard he would think twice of doing it again.
It seems practically no-one else outside of the elves, daemons and Lizardmen (a few Slann dropped by to strengthen it) in the Warhammer world knows about this super uber important vortex though, which kind is weird since it is important to their survival. Perhaps the elves think no one would believe them or they are following in the footsteps of the USA in keeping secrets with unnecessary importance.
It is the central MacGuffin of Warhammer 2 Total War.
