- "…Storm the battlefield with Tyth, god of rage. The Firstborn of Izax and Scyva leads us to victory against the profane outlanders. Raise your bloodied fist and cry triumph…"
- ―"The Awe of Tyth," part of a Zakuulan devotional text
Tyth, the Firstborn, was the warrior god and avatar of rage among the six primary Old Gods, the deities worshiped by the people of the planet Zakuul prior to Valkorion's ascension to Immortal Emperor. The first of the four children of Izax and Scyva, Tyth was accompanied on the battlefield by his sister Aivela, and Zakuulans believed that Tyth would lead them to victory against outlanders .
Tyth originated as an experimental Iokathii wardroid, built by an ancient, but highly advanced people. He, along with his five brothers and sisters, were tested on several unsuspecting worlds, leading to over ten trillion casualties. One of the worlds tested, Zakuul, would eventually come to worship the machines as gods, naming Tyth the god of war and rage. Even to the years following the Treaty of Coruscant, Tyth was still worshipped by many on Zakuul.
Tyth would reappear to be the first of the six wardroids to reawaken. He was defeated by the individual known as the Outlander shortly after his reactivation.
