SB-25

The SB-25 was a type of oddly-made droid in operation as of the time of the raid on Kessel in 10 BBY. A rusty SB-25 unit worked in the control center of one of the spice mines of Kessel, and was present while Qi'ra engaged in aggressive negotiations with the Pyke Syndicate director Quay Tolsite.

Behind the scenes
The SB-25 servant droid first appeared in Shabby Blue's Legends erotic fiction "The Slave Princess", and was introduced into erotica canon with a brief appearance in Kooriv's 2018 fiction "Qi'ra's Aggressive Negotiation".
