Atollon

"This planet may be hot, dry, and unpleasant... but at least there's nothing trying to kill us."

- CT-7567, before he was attacked by Atollon's wildlife

Atollon was a remote planet in the galaxy. In the third year before the Battle of Yavin, the rebels went to Atollon and established a base after receiving intel from rebel astromech Chopper and AP-5, an inventory droid in service of the Empire.

Geography
"The site doesn't look like much, I'll admit. The good news is our scouts found a fresh water source deep underground."

- CT-7567

Atollon was located in an undiscovered zone, off a major hyperspace route. The planet had a breathable atmosphere, but a hot climate. Despite the dry weather on the surface, the planet featured a fresh water source deep underground. The planet had at least one cave which served as a hive to the giant krykna spiders. Atollon was also home to other creatures, such as the convorees and the dokma.

History
"We finally have a place to call home."

- Hera Syndulla, to Kanan Jarrus

In the wake of the near-destruction of the rebel fleet during many battles, the early rebellion against the Empire faced a shortage of bases for their forces. In the third year before the Battle of Yavin, the rebels finally found Atollon by cross-referencing rebel data with the Imperial network, provided by AP-5, and successfully established the Chopper Base. After the sudden disappearance of rebel Lieutenant Dicer, they found out that one of the planet's native creatures was the Krykna, a giant spider-like predator. Eventually, they managed to ensure the base's protection using the sensor markers as a fence.
