Khareth
The Khareth call themselves Kha'reth — those who awaken the heart of worlds — and the name is doctrine, not poetry. Born to a metal-rich world under a crushing atmosphere, their entire civilization rests on extraction: not as an industry bolted onto a culture, but as the culture's founding act. Ancient, patient, and unhurried, they are the Expanse's deep-world people, cool blue-grey against the Human and Dralvok crews they crossed with.
