- "In case you forgot, Peragian Fuel explodes at high temperatures! That's what blew that chunk out of Peragus II and made this asteroid field in the first place!"
- ―The Peragus Mining Facility Security Head
Peragian Fuel was a kind of fuel found only on Peragus II. It was extremely volatile, and was almost exclusively mined by the Peragus Mining Facility until its destruction at the hands of Darth Sion in 3951 BBY. Among its buyers was Citadel Station, which used the fuel to remain in orbit around Telos IV.
