- "The Yost system will not be safe for your friends at all."
- ―AP-5 interrupts Hera Syndulla, who was planning on retreating to the Yost system
History[edit | edit source]
Three years before the Battle of Yavin, after an extensive search for a secure world to house their base, the Spectres managed to cross-reference Republic and Lasat star maps and found that a moon of Berzite in the Yost system was suitable for the purpose. However, the trip was delayed as the rebels' stolen Imperial cruiser-carrier did not have enough fuel to make the journey. Thus, the Spectres traveled to Horizon Base to steal the fuel. There, one of the rebels, astromech droid Chopper, was separated and stowed away aboard an Imperial cargo ship. He soon befriended a protocol droid designated AP-5 and together they managed to steal the vessel. Upon hearing the rebels planned on stationing their base in the Yost system, the Galactic Empire set a trap there intending to stop them. When AP-5 heard where the rebels intended to retreat, aware of the Imperial trap, he instead recommended the planet Atollon.
