Trixie and Naeno, two of Bondo's top lieutenants, have a turbulent relationship. While Trixie prides herself on ruthless efficiency, Naeno is the embodiment of chaos while behind the wheel. The only thing they have in common is their penchant for senseless violence, which they enjoy dispensing on anyone foolish enough to wander into their territory.

As the respository for the city's refuse, the Under Junk is a prime target for gnomes from Bondo's gang who intend to steal valuable mechanical components.
