Seven represented a K droid's designation, a creation of the droid J-6 located on Aricho. These K droids were constructed with the purpose of providing assistance to the planet's resistance, with the goal of freeing its inhabitants from the dominion of the Nihil marauders; however, Seven was not fully operational. During an encounter between the Jedi Knight Vernestra Rwoh and J-6 on Aricho, J-6 asked for her assistance in extracting the energy core from a speeder bike to be used for Seven.
