Ajalo Nills, a male Arcona who possessed the Force-sensitive trait, made his living as a mercenary in the final years of the Galactic Republic.
Nills belonged to a mercenary outfit under the command of Dantin Vellos, a Zabrak. The mercenary band was contracted to journey to the Cularin system and assassinate Osten Dal'Nay, the head of the Cularin Militia, upon the arrival of the Ithorian herdship called the Bazaar. Nills went along with the team, and they set up an ambush for Dal'Nay on the planet of Cularin. After Dal'Nay escaped into the Cularin jungle, the mercenaries gave chase. Ultimately, they cornered him by a creek and engaged him in close combat. However, the heroes of Cularin intervened, launching an assault that resulted in the defeat of Nills and his fellow mercenaries.
