Hello everybody! Many should be familiar with the one of the newer factions to join 40k. Thats right kids, the Tau! Kids huh? You implying that little kids play the Tau. Insolent Gue'saal! --NecrusIV-(Talk) 11:16, July 1, 2012 (UTC) As the Tau selflessly follow The Greater Good, the equality and peaceful union between all races to the betterment of the galaxy, they allow other races to join their empire. Examples of the aliens under the banner of Tau'va include the Kroot, Vespid, Nicassar, and most infamously, the Imperium of Man.
