At least one member of this species became a Jedi Knight; Bazel Warv was a contemporary of Valin and Jysella Horn and gave his life while protecting Allana Solo.
Ramoans were larger and stronger than average Humans. Their skin was jade green. They had small eyes, a pig-like snout, and tusks jutting out of their mouths. They spoke in a series of grunts, oinks, and squeaks. The shape of their mouths made it very difficult to speak Basic. They may have been related to Gamorreans.
Bazel Warv is the only Ramoan to have been given more than a background role. Initially, in the preview of Fate of the Jedi: Omen included with Fate of the Jedi: Outcast, he was said to be a Gamorrean, and most aspects of his description could be applied to either species.
