Led by Colonel Jack O'Neil and Daniel Jackson, the Abydan refugees left Earth for a world they could call home. Instead they found hell...
Earth's Stargate link to planet Ballas is broken, leaving the Abydan colonists stranded - and stalked by a merciless enemy. Believed first to be primitive beasts native to Ballas, these cat-like predators arrived through the Stargate - possessing superior firepower and innate military cunning. But who are these aliens, and why are they on Ballas? The answers lie in the secret past of an alien race - a race that is all too familiar to O'Neil and Jackson.
