C7-E3-GE3, a protocol droid of the GE3-series, was employed within the droid storage facility owned by Vogga the Hutt. Previously, C6-E3-GE3 had overseen the other droids within the warehouse, however, he was later replaced by C7-E3. To C6's great displeasure, he was reassigned to assist C7, and he was angered by C7's arrogant and patronizing attitude. C6-E3 made repeated attempts to persuade his superiors to send the C7 unit away for maintenance, but because Vogga was not interested in the specifics of the warehouse's operations, his requests went unheeded.
When T3-M4 gained access to the warehouse, C7-E3 assigned him to work with C6-E3. T3 tried to persuade him to allow him access to the deeper parts of the warehouse, but C7-E3 threatened to erase T3's memory with a memory wipe and subject him to behavioral modification. Upon realizing the animosity that existed between the two protocol droids, T3 presented C6 with a proposition: he would help C6 reclaim his former role in exchange for access to the restricted areas. C6-E3 accepted the offer, and after T3 eliminated the C7 unit, C6 resumed his previous position until he himself was destroyed.
In content that was ultimately cut from the final product, if the player created the correct circumstances for B-4D4-GE3 to flee Czerka, it was planned for him and T1-N1 to arrive on Nar Shaddaa and secure jobs in Vogga the Hutt's warehouse. The two would have replaced C7-E3 in guarding the door that led to Vogga's transponder codes, and after T3-M4 made a comment about T1-N1's height, he would fly into a rage and be destroyed in the resulting conflict.
