Irgal Nirmath was a trapper living in the Fangwood in what was then the northern reaches of Molthune. Unhappy with the centralized control exerted by the southern capital of Canorate, he joined the side of the rebels in the Freedom War. He became a commander and was able to organized the disparate forces into a single, sizable army. Thanks to his leadership, the rebels were able to start winning victories and his legend spread. They renamed themselves Irgal's Axe and through cunning and guerrilla tactics were able to force the Molthunian forces to surrender and allow them to succeed. On the very night of their victory, however, Irgal was slain by an assassin. In his honor, the fledgling nation took the name Nirmathas.
