Obsidiawn

The mightiest fortress and de facto capital of the Crystal Kingdom, the Obsidiawn is a mobile castle of some kind that travels the kingdom, giving military aid where needed. Also called the Floating Fortress, no outsiders understand the means by which the insular kingdom allows their castle to move about.
Though he cannot always be found there, Obsidiawn is the official seat of Crysos the Just, who rules the Crystal Kingdom.
