I have begun examining the strange aura surrounding this tower. The bricks of the tower are protected by a curse, stronger than any I've seen before. The magic from the curse is boiling off into the surrounding area.

A breakthrough! In my journeys I sighted a huge snake-like monster in a decorated courtyard. Nearby, I picked up a worn down, discarded green scale.
The magic in the scale seems to have the curse-breaking properties I need, but the magic is too dim. I may need to acquire a fresher specimen, directly from the creature.
