Thain was an Imperial planet before being invaded and probably consumed by a Tyranid Hive Fleet. Thain orbits two suns, and was known for its large grox herds which formed the basis of its economy.[1]
History
At some point, Thain was invaded by Tyranids. The Imperium initially intended to defend the planet, dispatching Astra Militarum forces and an Imperial Navy contingent. The Imperials deliberately destroyed the planet's wildlife and domestic animals, using scorched earth tactics to slow the Tyranid advance. Despite these efforts, they were gradually pushed back by the Xenos invaders. Eventually, the Imperial position detoriated to the point that the battle was considered lost, although this remained unknown to the Astra Militarum garrison.[1]
However, the Adeptus Mechanicus dispatched a suicidal mission led by Magos Procrustes to Thain, intending to capture and study a new Tyranid bioform observed on the planet. With support by the Cadian 32nd's Fifth Company, Procrustes achieved his objective and consequently transmitted the data offworld. Afterwards, the Adeptus Mechanicus contingent committed suicide with acid to deny their biomass to the Tyranids, while the Astra Militarum troopers fought to the death.[1]
