Gil'Dishpan/Gil'Dan

Methane-breathing aliens from a gas giant in the elliptical galaxy O-749. First contact with human race in 2753 AD. Their political position has remained neutral at all times. Frequent mediators of disputes between sentient races due to their disinterest in oxygen/nitrogen biospheres. (Classic continuity)

The Gil'Dan, previously erroneously translated into Interlac as Gil'Dishpan, consist of two races. The dominant race are in the form of brain globes; the under-race are the familiar purple slugs. (Earth-247 continuity)
