Empty Palace of Melek Taus

From PathfinderWiki

The Empty Palace of Melek Taus is an enormous, empty steel-walled castle on the slopes of the celestial mountain of Heaven that once was the home of the empyreal lord Melek Taus. Beautiful silver flying buttresses adorn its ramparts, decorated with gemstone murals showing Heaven's greatest victories against the forces of the Outer Rifts and the Maelstrom. The palace now lies completely empty and open, with no archons patrolling its walls, but her former servants believe that Melek Taus will one day return.1
