Sabaton was a formerly-controlled Bulwark Sphere dedicated to the management and control of convicted prisoners and psychologically disturbed individuals deemed too dangerous to keep near the public. It is mostly tundra and forest, with very few large bodies of water. The old, broken prisons on its surface are condemned and considered haunted. Nobody guards it, nobody really lives on it. After a horrifying necromancy incident overran the prison facilities, the entire sphere was abandoned and the old prisons were permanently and magically locked. It's spoken of in hushed tones as Bulwark's dirty little secret.
