Clockwork creatures reside on Mechanus in a realm called Regulus and seem well suited to it. These alien beings, called modrons, look and act like constructs but breathe and eat like the outsiders they are. The modrons control sixty-four cogs, and this number never varies.
In truth, modrons outwardly hold many traits in common with inevitables, but modrons are concerned with maintaining their own ordered society, not punishing other creatures for broken laws. The formians have yet to test the modrons' strength, although such a conflict is likely as the formians continue to expand.
