Cawfee

Cawfee was first bred by a farmer in the Scorched Lands, the technique was later thought to be lost when the empire burned the region. Later, as the Knights Republic formed, it was rediscovered and used as a way to boost the rebellions fighting potential and gave them the ability to defeat the Empire's android armies.

Effect on Humans
Cawfee has a rather unique effect on humans, when prepared correctly, it can increase the strength and speed of a user with little to no negative effects or lasting consequences.
