POC3 was a volcanic world in the Colonies region of the Galaxy. It was populated by Humans and specialized droids called firewelders, or "Dragons".
The droids revolted under the leadership of HK-78, and a resistance was formed, called the POC3 Dragon Slayers. Thanks to Jedi Masters Nathaniel Kenobi Solo and his wife Jaina Solo Kenobi, the droids were defeated.
Behind the scenes[]
POC3 and the POC3 Dragon Slayers are all anagrams of C3PO's name.
