This fabled city—along with the ruins of its sister city, Io’vakas—lies in the south of the Vast, deep in Argonnessen

An experiment started 3,000 years ago by a small cadre of dragons known as the Warders, Io’lokar and its ruined sister city of Io’vakas are considered myths even by many inhabitants of Argonnessen, and are rarely heard of at all beyond the continent. Humanoids of nearly all known races, brought together by the Warders and allowed to develop on their own with only moderate draconic interference, are Io’lokar’s sole inhabitants. The city is protected by great magic wards, and many of its residents are potent warriors or casters. The city is as rich in magic as Sharn though far less ostentatious, lacking such obvious wonders as floating towers. Many dragons still desire the destruction of Io’lokar, begrudging its population even the modicum of draconic magic and knowledge granted to them by the Warders, but the city’s wards and isolated location have kept it safe.
