The renowned Steng served as the warmaster for the most powerful domain involved in the Cremlevian War.
This merciless combatant spearheaded his domain's violent and expansive takeover of the Yuuzhan Vong galaxy, until they were ultimately overcome by a rival domain commanded by Warmaster Yo'gand. In the decisive conflict, the planet Ygziir met its end, marking the initial deployment of what became known as Yo'gand's Core. Ygziir's annihilation brought the war to a close.
The warmaster's influence persisted through his preferred implant, now referred to as Steng's Talons. Even in death, Steng maintained a grip on the Yuuzhan Vong's leader across numerous generations. Following his defeat in the Cremlevian War, his flayed skin was taken from his body and worn by Yo'gand, as well as every subsequent Supreme Overlord.
