LongestRoad Inevitables

Zelekhut, Kolyarut, and Marut.

The Inevitables are creatures of clockwork from the plane of Mechanus. Each is tasked with hunting down a particular type of rule-breaker. They are thusly:

• Zelekhut. These represent the ineluctability of justice. They are extremely skilled trackers and usually hunt those who flee to avoid punishment. They resemble mechanical centaurs and use built-in spiked chains charged with electricity as their primary weapons.
• Kolyarut. These represent the ineluctability of agreements. They hunt oathbreakers, often assuming humanoid form. Their natural forms resemble humanoids made of black metal, with red robes. One of these gave a Mercane head to Saula. Delicious!
• Marut. These represent the ineluctability of death. They hunt for those who either extend their lifespan unnaturally (such as liches) or those who commit extreme acts to keep themselves from death (such as sacrificing hundreds of others to save themselves from a plague). One of these was stomping around the Plane of Air city where the party was staying, but Ezel cast some aura-confusing type spell to make sure he didn't get targetted.

Not pictured here (but Ezel found out some about them when researching):

• Varakhut. These protect the integrity of divinity by hunting down beings who are attempting to ascend to godhood. Should the attempt be successful, however, the varakhuts will defend the new god as part of the natural order, as they are also tasked with hunting down any being who attempts to kill a god.
• Quarut. These protect the integrity of space and time, usually against wizards with the power to alter reality with wish spells or time travel. They resemble metallic humanoids with hourglasses for heads.
