Threat Analysis - Krell

“The Conflict Age, over a thousand years ago now, yet the images still seem as clear as though it were yesterday. In those countless years the Kilneck fought alien races so uncompromisingly cruel, it were as if they’d been conjured from some dark fairy tale. The Heracleum, The Root Dogs, the Darol Ragen were among the worst. But for sheer ferocity, and the desire for ceaseless bloodlust the Krell were unrivalled.”
