The bravest of the Propros-kin warriors, Nimni led the charge of the Porpros-kin against the Hero’s castle, believing a command given by the Order that they would return their sacred relic, the Beads of the Priestess, if they obtained the Chronicles owned by the Hero’s Company. By traveling through the water up river, they were able to sneak past all of the Company’s scouts, but the Hero was able to repel them.

Nimni returns to Naineneis, where the giant shell is shut off from all humans. Through Cougar, the Hero is able to gain admittance to the shell, where he explains his side of the story. When the Hero offers to obtain the Beads of the Priestess, Nimni accompanies him. He points out the beads, as well as the giant Renegade that guards them. After the Beads are recovered and returned, the Porpros-kin ally with the Hero. The aquatic abilities of the Porpros-kin were sought by Liu to help take Ladzaa Fortress, and Nimni, along with his fellows Nemne and Nomno, participate in the plan fully.

Although Nimni is a bid timid and easily moved, he never lacks in bravery and eagerly works at the right hand of Priestess Neira. Chrodechild speculates that due to their natures, Nimni and Guntram would get along very well.

After the war ends, Neira retires from politics and Nimni is installed in her place. Although reluctant, he steps up to the job. - Matt620
