Asmodean Knot

The Asmodean Knot is a pocket demi-plane, created of shadowstuff, used by the Lord High Mayor of Westcrown as a personal vault. Being not of the prime material plane, it may or may not follow traditional rules of physics within. It is widely thought to hold many treasures, traps and horrible creatures and spirits.

The Knot was invented by Lord High Mayor Anvengen Doskivari, who was an powerful Asmodean cleric and engineer. He is presumed to have died in the Knot, since he never returned from it.
