My theory:
Saradomin leaves Teragard in the hands of his magisters, entrusting that they and the presence of his mortal daughter will keep his teachings in the hearts and minds of his fellow humans.
After Saradomin leaves, the magisters realize that though Saradomin authorized them to teach, he left no safeguard in the case of a rebellion or a schism (pun half-ass intended). Therefore, the magisters saw it proper to form a tribunal in order to deal out rulings and sentences in such cases.
Saradomin's absence being ever extended, the Tribunal found itself setting new precedents. From time to time, a case would fall to them that wasn't thought of when the court was originally established. As the Tribunal took on these cases, they grew in authority and power. Eventually, they had usurped total rule of Teragard.
Using the Schism, the Tribunal began seizing other worlds. Establishing themselves as an imperial force through the multiverse.
Adrasteia saw all of this happening, and sought to bring her father back home, but had no way of locating him, and no way of getting there if she were to locate him. She took to the Schism, seeking out worlds to which he may have traveled, hoping to find his trail.
The Obsidian Tribunal followed her, seeing her as a threat to their rule. Eventually, they captured her, and have been using some means to prolong her life to show her off as a forced figurehead, helping them maintain their grasp.
Unfortunately for them, they had never experienced Nex.
