Steintist's Lair

Kaigu, or Ryūgū-jō, the Dragon Palace of the Sea, lies a several-day swim beneath the surface of the ocean, in the watery abyss where all rivers, springs, and seas begin. The palace is made of gold, crystal, coral and pearl, illuminated by fish-scaled walls from within. It is surrounded by a garden with four sides, one for each cardinal direction and each corresponding to a different season. Time passes differently underwater, with one day equalling a hundred surface years or more.
