Taros

Taros is a desert mining world in the Ultima Segmentum that the T’au captured from the Imperium and renamed T’ros. The entry concerns the planet as the site of the Taros Campaign, in which Tallarn and Elysian forces of the Imperium failed to hold it.

The Imperium sought to retain the world’s mines, but the T’au kept the planet. Its water and ore were the principal resources at stake. The campaign is recorded in a detailed after-action report in the Imperial Armour publication series, and the name appears on the charts of both the Imperium and the T’au.

Taros remains a named T’au conquest that Imperial Armour treats as more than a minor skirmish. It is not the T’au homeworld, nor merely an episode of the later Damocles campaign. The entry retains its Ultima parent and its T’ros alias, and it does not classify the world as a core world of a T’au sept (a territorial division of the T’au Empire).
