Thrommel's Green Location D: The Hatted Tower

This stout tower was built by a magician friend of the towns founder 150 years ago. It includes a library, alchemical laboratory, a small dungeon for keeping interesting monsters locked up to study, and an observatory, as well as the living quarters for the town's resident wizard

It is called The hatted tower because the rooftop was made of tarred paper and canvas on a mechanical frame meant to allow the rooftop to fold down for the observation of the Stars. However, the design was deeply flawed and after a few high winds and hailstorms, the tower has come to look like it is wearing a crooked old steeple crowned hat.

The windows and doors of the tower are Wizard Locked to Abus and Mairi. The first floor is permanently protected by an alarm spell. The interior is lit with hooded lanterns imbued with continual light.

The current master of the tower, Abus, was little more than an apprentice when the aging elf who had once kept and taught at the tower died. He is partially self-taught from what she left behind.

Over the years Abus has defended the town enough to reach a modicum of power, and uses his magical abilities primarily to help people find lost objects, mend severely damaged possessions, and settles community disputes.

Abus had studied the same time Rivia did, and can tell a little bit about her early adventures, but didn't keep in touch with her after she went further a field.
