Reversionist

The Reversionists are a faction on Cybertron, noted, and largely hated, for their piousnesses. They believe that Cybertron was once Primus, and so that every Cybertronian is in a small way Primus himself, and therefore that deceased Cybertronians ought to be cremated in a plasma pyre to return their substance to Cybertron, hence the name.

They seem to have a penchant for staffs and are known to revere the Titans.

The Reversionists practiced daily routines to exercise their faith. They listened to Heretech's lessons, performed chores, meditated, and prayed.

Gauging the Truth: Part One While the Exodus was in space, the Reversionists were not above wiping the memory of stowaway Gauge and placing her under the mentorship of Accelerator, while jailing Arcee and Greenlight in the engine room. Heretech announced to his followers that Primus had deemed them worthy of a planet of their own, declaring that they would land and cleanse the planet and take it for the Reversionists.
