Cyrlok

Pronounced SEER-lock
Adapted from the 5e Monster Manual "Modron":
Cyrlok are beings of absolute law that adhere to a hive-like hierarchy. They inhabit the plane of Machina and tend its eternally revolving gears, their existence a clockwork routine of perfect order.
Absolute Law and Order. Under the direction of their leader, Primus, Cyrlok increase order in the multiverse in accordance with laws beyond the comprehension of mortal minds. Their own minds are networked in a hierarchal pyramid, in which each Cyrlok receives commands from superiors and delegates orders to underlings. A Cyrlok carries out commands with total obedience, utmost efficiency, and an absence of morality or ego.
Cyrlok have no sense of self beyond what is necessary to fulfill their duties. They exist as a unified collective, divided by ranks, yet they always refer to themselves collectively. To a Cyrlok, there is no "I," but only "we" or "us."
Absolute Hierarchy. Cyrlok communicate only with Cyrloks of the came CR or within 1 of thier CR Cyrlok more than one CR away are either too advanced or too simple to understand.
Cogs of the Great Machine. If a Cyrlok is destroyed, half its volume is returned to Machina. A replacement from the next lowest rank then transforms in a flash of light, gaining the physical form of its new rank. The promoted Cyrlok is replaced by one of its underlings in the same manner, all the way to the lowest levels of the hierarchy. There, a new Cyrlok is created by Primus, with a steady stream of Cyrlok leaving the Great Cyrlok Cathedral on Machina as a result.
