Wizard Zugzwang
From MHWiki
Wizard Zugzwang is a mysterious figure mentioned in the description of Zugzwang's Last Move. He is apparently responsible for the various traps traded in the Gnawnia region. He lives in a tower overrun by "clever" mice, although its exact whereabouts are unknown. While he originally created Zugzwang's Last Move to combat the tower mice, hunters have found it to be equally effective in the Furoma region.
