In 5 ABY, the Central Committee of Grand Moffs organized an important meeting on Kessel in order to gather the most Imperial forces on the planet. After have learnt the existence of this convocation, the Senate Planetary Intelligence Network under Mon Mothma sent R2-D2 and C-3PO on Kessel to spy the event.

- ―C-3PO, to R2-D2
R2-D2 and C-3PO were disguised as Kesselian droids (as they were far too well known to afford undergoing the mission as-is) and landed on the planet in a drop pod covered as a meteor. They reached the capital Kessendra and the Stadium where took place the meeting.
During the convocation, Grand Moff Hissa presented the Supreme Slavelord Trioculus as the son of Emperor Palpatine. Trioculus declared himself the rightful ruler of the Empire and demonstrated his power by blasting a critical Grand Admiral and Royal Guard with a lethal dose of Force lightning.
After the meeting, the two droids tried to escape the planet but their transport was detected and destroyed by Imperial LAVr QH-7 Chariots. They were about to be located by stormtroopers when they were rescued by Jedi Knight Luke Skywalker. The trio reached the Stolen Imperial Command Speeder 714-D used by the Jedi to land on Kessel. Pursued by Imperial Chariots, the ship piloted by Admiral Ackbar managed to leave the surface, destroying some enemy speeders on its way. In orbit, the speeder was detected by probe droids but they eventually managed to escape in a radioactive asteroid belt.
