Pureblood

Sontara, the home world of the Sontarans is about to fall. Their mortal enemies, the Rutans, are the apparent cause of their demise, but Marshal Stave and his men have little time to analyse the situation. They have only enough time to load the racepool into his flagship, the Warburg, and get into the comparative safety of space. The ship narrowly escapes as Sontara explodes.
