Quadravidia

Quadravidia was a planet to which no segmentum or parent sector is attested in surviving records.

In 992.M41 the world was attacked by forces of the T’au Empire.

The attack formed part of the episode recorded in the novel The Greater Good, in which Commissar Ciaphas Cain took part in a truce with the T’au against an approaching Tyranid hive fleet.
