Damaged ship of Triannon zealots who worshipped the Sphere-Builders and used a rescue to seize Enterprise as a weapon for their holy war in Chosen Realm.
The Triannon ship was carrying a group of Triannon religious zealots led by D'Jamat when Enterprise came to its aid in Chosen Realm. The Triannons revered the Sphere-Builders as the Makers, and their world was torn by war between sects who disagreed over how many days the Makers had taken to build the spheres.
Once aboard, D'Jamat and his followers, some carrying bombs inside their bodies, seized Enterprise to use against their rivals. Archer retook the ship, but D'Jamat found his homeworld already devastated by the fighting.
