The Inaccessable Castle

 Deep in the land of the Dark Knights, is the Inaccessible Fortress of the witch Tzaantzch. Similar to other fortresses made by Tzaantzch, the castle is different depending on the viewers mind. Some see it as a giant crystal glowing in the darkness, while others perceive it as walls of blue fire and pillars of bone. No matter who views the fortress, it is always changing. Spires and towers constantly change and vanish making it cofusing for anyone who dare enter it.
