Kelpien

"Your world has food chains. Mine does not. Our species map is binary; we are either predator or prey. My people were hunted, bred, farmed... we are your livestock of old. We were biologically determined for one purpose, and one purpose alone – to sense the coming of death. I sense it coming now."

- Saru, 2256

Kelpiens were a sentient humanoid species.

History
