Swampie

Swampies are a sapient species of green-skinned humanoids originally from the planet Delta Magna. When Humans colonized their world, the Swampies were forcibly relocated to the marshlands of one of the planet's moons. Eventually, the relocated Swampies developed a new religion worshiping the gigantic beast named Kroll.
