Kolborr Engine

The creature can take 3 legendary actions per round, choosing from the options below.

The Kolborr Engines are relics of the Sarnic Foundry, a pre-collapse arcology where artificers fused crystal storm-cores with forged colossi. Only a dozen were finished before the Foundry's fall; scavengers and warlords prize their husks, while a few still patrol old battlefields, following the long-buried directives that once ensured the Foundry's survival. Scholar Verim Hoss, in his treatise On Foundry Ethics, argues the Engines are not mere weapons but autonomous guardians whose priorities have slowly calcified into obsolete protocols. Most Engines are solitary and territorial, prowling ruined industrial plateaus, dam ruins, or the iron-forests of the Gearglades where stray lightning feeds their cores. Tribes such as the Iron Cantors (salvager-priests in the city of Palys) worship them as divinities of order, while the League of Circuit-Menders studies them to recover lost principles of magitech. When encountered in the wild, a Kolborr Engine follows ancient routines: it clears obstacles, seeks lost Foundry transmitters, and neutralizes perceived threats with efficient, uncomplaining force.

Visualize a vast humanoid frame almost as tall as a cathedral doorway: broad shoulders armored in overlapping riveted plates, piston-thick limbs bound with braided copper conduits, and a torso dominated by a circular storm-core recessed beneath a hinged lattice. Its head is a faceted sensor array—no eyes, only a vertical slit of prismatic lenses and a ringed antenna crown. Fingers end in articulated manipulators that can crush masonry or delicately operate control valves. Surfaces are pitted and scorched, seams leaking phosphorescent coolant; welded rune-plates and faded Foundry sigils are visible along its forearms. Scale: stands roughly three times a human's height, capable of dwarfing a standard inn doorway; when in ruins it seems as large as a small watchtower.
