The 196th Iotan Gryphonnes were an elite Tempestus Scions regiment of the Ordo Tempestus that was wiped out after a failed mission to assassinate T'au Earth Caste personnel on the Sept World of Bork'an, a centre of learning and academia.
In 939.M41, the 196th Iotan Gryphonnes were deployed in their entirety by Lord Commissar Tilenus to the T'au Sept World of Bork'an to target the planet's academic facilities and wipe out every scientist, researcher and student. This would greatly affect the T'au Empire's ability to mass-produce prototype weapons and deadly Battlesuits. In the first few hours of the war, the Gryphonnes' Valkyrie-borne attacks were met with great success. However, the Tau's vicious counterattack, spearheaded by experimental Battlesuits and prototype weaponry, quickly overwhelmed the attacking Scions and virtually annihilated the 196th Iotan Gryphonnes. The Earth Caste scientist made good their escape during the battle, putting them out of reach of their would-be assassins. The few surviving Scions requested to be extracted; however, their repeated requests were denied, and soon they were systematically hunted down Bork'an's' vengeful Fire Warriors.
