Great Seal of Aethleas

A massive magical barrier errected in caves beneath the ruins of Aethleas, the Seal prevents the Chaos trapped beneath it from spreading into the rest of the Shattered World or the Planes beyond.

Also trapped beneath the Seal are the survivors of the great war that destroyed Aethleas, although they are presumably corrupted by the Chaos that has infected their home.

The Seal is maintained and guarded by a race of mechanical soliders, once weapons used in the apocalyptic war that destroyed Aethleas but subsequently reprogrammed by a questing Warrior Adventurer from Mantoni.

The Great Seal was originally powered by the Starshield Helm, but when that was reclaimed by the Knights of the Silver Cross they left the artefact-sword Onostothorin in its place.

The Knights of the Silver Cross were also given a number of magical weapons by the Seal's guardians - these Aethleas Swords and Aethleas Bows are also relics of the war and are quite powerful items.
