The Devoted of Morali
From Star Trek: Theurgy Wiki
Sarresh Morali was originally from the same time as the rest of them on the ship, but was recruited to serve on the 29th century timeship USS Relativity at a young age. He returned to his original timeline after the Niga Incident volunteering to aid the USS Theurgy on her mission.
Morali underwent MEM (Memory Engram Manipulation) treatment to keep his knowledge of the future from disrupting the time stream. Moreover, he had an implant installed in his head that had tech that could detect a temporal breach. When such a breach happened, Morali regained his memories so that he could try and thwart the enemy threat to the USS Theurgy. This was the reason why Morali was mission-essential in opposing the usurpers in Starfleet Command.
The Devoted of Morali were low ranking crew - often NCOs - aboard the USS Theurgy that were desperate for answers, and thought that the Morali had them, even if he was just as much flesh and blood as the rest. They became a following before the Battle of Starbase 84, and after it, they had become a serious threat aboard the USS Theurgy, in how they resorted to violence in order to try and make Sarresh Morali the commanding officer of the ship.
