Ascalon, otherwise known as the Mirrorworld.  If there were a centre to all of creation, of all realms and worlds, Ascalon would be it.

It is a world permeated with magic and filled with wonders from a multitude of worlds.  It's an ancient world whose long history is remembered by a precious few.  It is also a world that has seen it's own share of wars, fighting and terrors.
