Important keep from Old Empire times, at least 700 years old
Had a magical barrier guarding the keep
Destroyed 150 years ago in a blood ritual starting from the Crypt deep under the Keep.
Released magical energies corrupted the ground and made the area impassable.
Over the years the barrier kept shrinking as the magic was depleted.
Giant eagles in the tower, some of them corrupted by lightning
Undeads and animated armors, statues and weapons on lower floors
