Origin: Alpha Quadrant. A humanoid, spacefaring species whose space bordered the Cardassians and Federation. They fought non-threatening but bloody border wars with the UFP as late as 2357, but have been at nominal peace since; entry into each other's space is not seen as an automatic act of war. One of their customs is the adoption of the sons of enemy commanders killed in battle.
