Kyrthosum

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

Legend holds that Kyrthosum predates the gods' treaties with the world, birthed in a time when the planet still stitched itself together from molten seams. Some sages in the order called the Cartographers of Nareth claim Kyrthosum is a failed world-soul — a body meant to hold oceans and skies that instead awoke with the sentience of stone. Coastal tribes tell of a single colossal eye, a crater filled with a reflective lake, that watches horizons for threats. Kyrthosum wanders in long arcs measured in years. It favors tectonic rifts, polar wastes, and deep oceanic trenches where its vast feet can sink and recalibrate. It rarely approaches dense urban centers, but when it does the results are ruinous: whole provinces are re-sculpted, rivers rerouted, new hills born overnight. A handful of cults revere Kyrthosum as a remaker — the Ashford Synod keeps pilgrimages on the flanks of minor walking stones said to be its offspring. Scholar Vesmir Tollen wrote the seminal volume Atlas of Wandering Stones after documenting five Kyrthosum landfalls; his maps, inked with strange sigils, are coveted by rulers and feared by seafarers.

Kyrthosum resembles a living continent: ridged granite ridges rise like plated shoulders; basaltic spines form a crown along its back; slow, lichen-covered plains slope into bristle forests of petrified trees. Rivers of actual water, threaded with mineral veins, course across its flanks and fall in cataracts from cliff-like flanks when it moves. Its 'head' is a hooded mesa with a single vast pool of still water framed by a circle of standing stones; when Kyrthosum blinks by collapsing a fumarole, steam vents across its face. Scales are not scales but layered strata — veins of quartz, mica, and iron glinting in sunlight. Tiny settlements that cling to fissures give scale: a single human caravan looks like an ant trail on a pebble-strewn slope.
