Necessary Evil by Grimbald
Monstrous warriors of the V'Sori
The stuff of nightmares, the K’tharen are monstrous, slavering aliens — as fearsome as they are savage. Most are well over 7’ tall — every bit of which is muscle. The “fins” have humanoid forms but with a thick crocodile-like hide. Their head has a distinctive shark-like appearance, especially with the fin-ridge that runs along the top of their skulls and their coal-black eyes. Their coloration runs towards the darker end of the spectrum along their backs, from light greens to blue and violet, while the front is universally pale.
The K’tharen grow darker along their dorsal ridge as they age, and older members of the race can appear pure black.
