Tzeotine
this thick resin was produced in copious amounts by the plantlife that dominated the planet Parcelus Minor. Tzeotine was used by the inhabitants of the planet as a fuel source for lamps and heat, and refined it for use as a motor fuel. The presence of so much tzeotine in the plants proved deadly to the planet during the Clone Wars, when a rogue Separatist general ordered an orbital bombardment of Parcelus Minor. The blasts ignited the tzeotine that was in the plants, setting the entire planet on fire in a short time.
