The Alimbic species had a unique exoskeleton that enabled them to survive the harsh environments of the planets Alinos and Arcterra, as well as enlarged forebrains that have helped them avoid situations that could have led to the destruction of their race and granted them potent psionic abilities. Alimbics appear to have two armlike appendages, and possibly three legs (as does the Alimbic-mimicking Gorea). The race exhibited a floating head with a single eye, but no visible mouth, similar to the Kriken (which may suggest divergent evolution). This would indicate that the Alimbics used their psionic abilities to communicate telepathically, even before they were reduced to telepathic entities.
