Domain Steng was one of the early Domains among the Yuuzhan Vong. During the Cremlevian War, the Domain was led by Steng, the first Warmaster. They were one of the most powerful Domains among the Yuuzhan Vong. They battled with Domain Yo'gand for control of the Yuuzhan Vong galaxy. Eventually, the Domain was driven to Ygziir, where they dug in. Yo'gand, the leader of the rival Domain, eventually destroyed Ygziir by dropping its moon onto the planet, in what became known as Yo'gand's Core. Domain Steng either surrendered or was wiped out.
