When last spotted over a year before the Puncture, Mestari was a villainous human wizard of bizarre and inscrutable motives. He appears to be a collector of magical rings, from lofty polymorphing rings to lowly rings of the ram, ready to steal and murder for the sake of their acquisition. This obsession could be called a monomania if not for Mestari’s evidenced fascination with Seth Mase, for whom Mestari has more than once gone out of his way to make trouble. In the past Mestari has orchestrated the theft of a ring belonging to Seth, abducted Seth and placed him in a fortress of magical traps, and lured Seth back to the same fortress for no discernible reason without so much as making an appearance. He is also believed to have attacked Seth through an invisible stalker while Seth was afield in the Plains of Dust, though the lone stalker could hardly have dispatched Seth’s entire party.
Mestari has not been seen since the Puncture. It is not known how the strange cosmic disturbances may have warped him.
