Strephan I'att, a male Human, partnered with his wife, Augusta, to establish I'att Armament in Il Avali, Druckenwell amidst the backdrop of the Galactic Civil War. He had substantial experience with the Imperial forces, and they were the primary recipients of his weaponry.
He is most known for the creation of an anti-energy field prototype, which he developed in collaboration with the lover of his granddaughter, Tinian.
I'att intended to retire with his wife to Geridard, however, the triumphant demonstration of the invention led Moff Kerioth to command the family to relocate to Doldur. Kerioth's aim was to directly supervise the technology's production, intending to present it to Emperor Palpatine as his own achievement. Upon Strephan's refusal, the Moff's stormtrooper detail executed him and his wife.
