Wizard Zugzwang
From MHWiki
Wizard Zugzwang is a mysterious figure first 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. 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.
A page from Plankrun's Journal reveals that Plankrun had personally received Zugzwang's Last Move from Zugzwang.
Zugzwang's pet octopus, Bubbles, guards the entrance to the Seasonal Garden and Zugzwang's Tower.
