Pellians

The Pellians are a highly xenophobic, non-humanoid race native to the Pelia Sector of the Alpha Quadrant. Previously limited to a single solar system, the Pellians began an aggressive scheme of territorial expansion in the latter part of the 24th century, leading to several border skirmishes with the Federation, culminating in the Battle of Pellia in 2389 which resulted in the loss of three Federation starships and over a thousand lives. Despite several sporadic subspace negotiations with the Pellians, no human had ever laid eyes on a member of their species until 2413, over fifty years after they were first encountered. James Copper holds the honour of meeting a Pellian face to face, and his reaction to its presence suggests they are utterly horrifying in appearance.
