The Painted World of Ariamis, as the name suggests, was created by Ariamis and is located within a painting, accessible from a cathedral in Anor Londo. It is a cold, snowy world with an old structure high atop a mountain and surrounded by cliffs. It was created to house the things that the Gods of Anor Londo feared.
The painting is protected by Painting Guardians who have watched over it for generations, though their reason for doing so is long forgotten.
This area is now home to the bastard Priscilla, the dragon-human crossbreed.
