The Seal of the Citadel (repeat)

A long time ago, an ancient force capable of both protecting and destroying was sealed in the bowels of the Citadel. Argonax, the guardian of the throne, has guarded this secret for centuries, but time is inexorable - the seal is weakening. We have found a way to restore it, but it requires a bit of the Guardian's own power. Only those who can defeat him are worthy to touch the ancient knowledge and receive the seal enhancement scroll.
