An island south of the shores of Hillsbrad Foothills, in a shape of towering spiral.
The island has mysterious, unknown history. It is haunted by ghosts of renegade paladins, monks and priests that for some reason are condemned and cannot find peace in death. They are called "The Banished", and are led by a spirit of a Paladin, Arados the Damned, who lives in a tower at the top of the spiral.
Before patch 1.10, the mobs on the Isle were only lev 20-30. Now they are 55+ elites, and have become part of the 0.5 tier armor quest.
