Now that the contest is over, I wanted to take the time to expand on the So'lai Pioneers that I submitted.
The Sol'ai Rift is, in my interpretation, is the name for the 'Perdus Rift' described in the Tau Codex map. As I understand it it is a vast frontier, bordering multiple Sept territories from Dal'yth to Vash'ya. This region would be plagued by everything from pirates, both Imperial and Chaos, Eldritch raiders and potentially even elements of the Tyranids from two centuries ago.
As described in my dataslate, these fringe colonies would have limited resources and fewer military units, all the more so with half of the Fire Caste now on the other side of the Damocles Gulf. Such 'Pioneers' would need to rely entirely on themselves for long periods of time, a decidedly unconventional formation for a race that approaches every situation with communality and interdependency.
My 'hero' unit of Pioneers serves in my Frontier Coalition army and is a combination of Tau from several Septs working in concert with the Shas'Ar'Tol in order to strengthen the border (I was inspired by the movie 7 Samurai).Partisan Force 0-7
Partisan Force 0-7 operates along the Tash'var border as a completely self sufficient force acting in both support roles but also as shock troops. Astride Yo'shi mounts (lit: one who is righteous) these bipedal saurians are a genetic offshoot of an omnivorous steed that Tau of antiquity rode on the savannas of their homeworld.Shas'Vre Tash'Var U'rokTash'var is a unique Sept in that its Sept Prime world is still largely uninhabited. This has bred survivalists of the highest ability and Shas'Vre U'rok is no exception. Formerly an XV-22 squadron leader, U'rok was wounded fighting the Orks in the Western Quarantine Zone. During his rehabilitation the prefecture where his convalescence home was situated in came under attack by Eldritch raiders, attacks that have multiplied since Shadowsun's advances into the Imperium. With an ad-hoc unit of Firewarriors made up of security squads and Firewarrior walking wounded, he lead a masterful defense of the facilities, bottle-necking the pirates at the entrances while leading civilians into the inner grounds until Tash'var cadres could arrive.
After this, U'rok assembled the Partisan Force 0-7 with the express purpose of strengthening defenses in regions like Tash'var that do not have the necessary numbers to secure the border.Shas'Saz'Nami'La Bork'an Ais'chel Nuo'ko'Wounded Hand' as he is known, is the sole survivor of the bodyguard team attached to Aun'Jaath who was assassinated on Bork'an when an Imperial kill force attacked that Sept. Deeply scarred by this event, Nuo'ko dedicated himself to a life of study to find and calm his troubled soul, living in the equatorial jungles of Bork'an as a hermit until he was recruited by U'rok.
He carries Aun'Jaath's honor blade into combat wrapped with dyed purple cloth in mourning for his fallen master. He inspires the members of 0-7 both his understanding of Sio't meditations and reminding the Firewarriors that, despite serving alone in the wilds of a hostile galaxy, they are never alone and are a part of the Greater Good.
Shas'La Tash'var Saa'riSaa'ri is a young Tash'vari warrior that held the rank of 'Saal when U'rok lead her and the students of the prefecture in its defense. Deemed as having passed her trials and raised to the 'La rank, she has been by U'rok's side ever since serving as his protege.
(I'll finish the other four later)
