- "Planet Insk: silicon-based, not carbon-based. No resources to mine. Off the list."
- ―Jan Dodonna
Insk was a silicon-based planet. General Jan Dodonna of the Alliance to Restore the Republic briefly studied it as a potential location for a new Rebel base after the evacuation of the Great Temple on Yavin 4, but quickly rejected it due to being silicon-based, rather than carbon-based, and because it did not have resources that the Rebels could mine.
