Stankaster Tower

This fire-blasted ruin once stood nearly a hundred and fifty feet high, the marbeled home of the Invoker Stankaster. What little reliable eyewitness evidence exists reports that a great magical battle, with fire, acid, meteor storms, and earth elementals, raged here for two days and a night in 581 CY, until the tower was breached. What has become of Stankaster, and who his assailant was, is a mystery.

Two adventuring groups that sought the answer did not return. Stankaster is known to have had two apprentices, a resident alchemist, and a visiting 10th-level Invoker, Karposhnen of Hardby, who was being trained when the attack came. Of all places reputed to hold magical treasures, this may be the best bet.
