I am sending a new race to the Amarillo Design Bureau that I have had in the works since college. The premise of the race is that they focused on salvaging enemy vessels. Thus their initial vessels had anti-shield weapons, and crew elimination dirty fission beams similar to fusion beams. They could hold their own against the other races, however during the Andromedan invasion circa 180, they were at a disadvantage since the Andromedans had no shields and were unaffected by the concussion torpedo.
Here are links to the different components of the Seldone Entente:
I also am submitting a space dragon scenario today.
