T'au sept flag

The flag of the T'au Sept, the homeworld of the Tau

A Sept is a partially autonomous colony of the Tau Empire. Each Sept has its own identity, culture, traditions, colors and symbols, much like an Eldar Craftworld or a Space Marine Chapter. Tau Empire Septs, however, are all deeply committed to the collective culture and the good of the Empire.

The identity of a Sept seems to be most affected by the caste composition of the population. Military doctrines also differ, although new colonies tend to rely on T'au methods until the colony "matures".

In late M41, there are more than 20 Septs in existence, although all are not known to the Imperium.
