The Drella are one of two humanoid species native to the planet Drell.
They once inhabited the southern continent of the planet Drell, living a primitive hunter-gatherer existence. However, when the Drellian plague wiped out over half the population of Drellians, several were offered positions as laborers for the Drellian government.
Eventually, the Drella were reduced to a form of slave labor and made servants of the Drellians. However, in 2614, a group of Drella and sympathetic Drellians led a massive revolution against the government.
