The 9th World Also simple known as "The Disc"

In a universe of infinite possibilities there exists all kinds of worlds. Some are great orbs floating in an empty void, some are leaves on the branches of an almighty tree, but this world is shaped like a great disc ringed by a huge range of mountains known to some as "The Teeth of the World" and they are over 100km high and can been seen from everywhere on the disc. Hidden in these mountains are the 8 great gates which lead to the primordial realms. Their influence flows into the 9th world, shaping it and it's people.
