The Twelve Tribes of T'Syriél were a coalition of representatives from the T'Syriél species on the planet, Shiva IV.


For years, the Twelve Tribes were at war with their Human neighbors, the warlords of the Calian Confederacy. In 3 ABY, a truce was declared between the two factions and a legal ceremony known as the Concordat of Peace took place in the capital city of Illyriaqüm.

A T'Syriél representative named Kéral Longknife forged a blood pact with the Calian warlord, Aron Peacebringer.
