Kyrthos

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

Kyrthos is one of the last known kolossi of the Asterion Forging, a cadre of artisan-archons who blended rune-craft and elemental smithing during the pre-Imperial age. Built as a city guardian and engine of reclamation, Kyrthos was cast in an alloy of bronze, star-iron, and trapped storm-stuff. When the Asterion citadels crumbled beneath tectonic convulsions and civil war, many kolossi were driven into the sea or neutralized; Kyrthos, however, activated and kept walking, following a directive its makers could no longer recall to anyone who might obey it. Survivors call the places Kyrthos passed the Sundered Asterion: terraces of polished bronze, ruined pedestals, and fields where trees were pressed flat into petrified fans. The Archive of Threvan holds the closest thing to a registry for kolossi; the archivist Mael Venn first identified Kyrthos from a fragmentary forging log and warned councils that these constructs do not 'die' like living things. Factions such as the Iron Conclave seek to recover Kyrthos for salvage, while the Order of Quiet Roads campaigns to corral or divert it—an enterprise that has cost entire caravans and one small fortified town.

Kyrthos stands roughly three times a tall human in shoulder height and approaches ten times human height overall; its silhouette fills a temple doorway. Its body is plate-like segments of hammered bronze riveted to a darker iron skeleton. Broad pauldrons are carved with bas-relief of ocean swells and forging hammers; its torso contains a circular, riveted vault in which a braided conduit of captured storm-light pulses faintly blue. Limbs are jointed with oversized bolt-hinges and pistons the size of wagon wheels; fingers end in blunt, chisel-like pads and can extend cable-hooks. Surface textures alternate between burnished shine and scabbed repair plates patched with mismatched alloys. Corroded glyphs and seam-lines seam its chest, while pitted scorch marks and polish scars tell of centuries of impact and re-forging. When moving, thin seams between plates hiss steam or sparks. Scale cues: show a human at knee height to emphasize Kyrthos's massive scale and a toppled gate or stone tower fragment in its grasp to communicate weight.
