Thinwick

Thinwick is a famous (infamous?) mage who used to reside in Morrick, capital city of the Redlands, before it was annihilated in the Penumbra invasion. Thinwick, and his hyperactive apprentice Kane, ran Thinwick's Magical Emporium, one of the most renowned magic shops in all of Sert. While Thinwick himself was not a master wizard (but neither one to be scoffed at), he was an experienced and creative inventor of spells and items, a leading researcher and developer of new arcana as well as an adept artificer and alchemist. Things could be acquired at his shop that could be found nowhere else (such as potions that gave a +1 inherent bonus to a stat for 10k, and occasional minor artifacts). Thinwick has even assisted the group personally in small ways, and took an active hand when Morrick was besieged by the forces of Neryk and its allies (this was before the Penumbra invasion), handing out magical items to the troops as well as flinging his own unique spells into the fray.

Kane, Thinwick's hyperactive apprentice, was found alive on the outskirts of Morrick after Penumbra destroyed it, but even Kane wasn't sure if Thinwick had survived. He is currently believed to be dead by most who knew him, although it seems odd that such a well-equipped wizard would have died in the face of several minutes' warning time...
