Kvariam Alpha

Kvariam Alpha is an Imperial ocean world in Ultima Segmentum, the seabed mining prize the T'au hid for a decade until Gunnar Red Moon's Space Wolves drowned their domes. This pin is that underwater war, not Fenris and not a sept.

Fire Warriors held the tiny land-mass; the real colony was cities on the ocean floor. Guard could not fight a league down, so Red Moon drove airtight Land Raiders along the silt, spilled Terminators into propeller-tailed battlesuits, and shattered the mining glass. The sea filled with xenos before the T'au ran.

Kvariam Alpha still matters as the Codex Space Wolves underwater fight. Unofficial summaries keep the Ultima parent and do not merge this ocean with Fenris or with Khollorn VII's later T'au conquest.
