Actions
Legendary Actions
The creature can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature's turn. The creature regains spent legendary actions at the start of its turn.
Lair
Lair Actions
On initiative count 20 (losing initiative ties), the creature can take a lair action to cause one of the following effects; it can't use the same effect two rounds in a row:
- Seismic Wake. The ground within 60 feet of Qarathul trembles. Each creature on the ground must succeed on a DC 18 Dexterity saving throw or be knocked prone; on a successful save, they take half as much damage.
- Crystalline Chains. Shadows of chains extend from the walls toward a target within 60 feet. The target must succeed on a DC 18 Dexterity saving throw or be restrained for 1 round.
- World-Anchor Concentration. A rune on the cavern floor flares. A creature within 120 feet that is concentrating on a spell must succeed on a DC 18 Wisdom saving throw to maintain concentration.
Regional Effects
The region containing the creature's lair is warped by its magic, creating the following effects:
- Within 6 miles of the lair, the ground is perennially unsettled; tremors are common and reveal hidden caverns.
- Subterranean waterways near the lair run metallic and cold, tinting the water with a faint iron flavor.
- The very air hums with ancient magic; spellcasting in the region is tempered by the weight of old bindings, slowing processes slightly.
If Qarathul dies, the bindings splinter for a generation, and the crust quakes for weeks as the world reclaims its freedom.

Lore & Description
Appearance
Qarathul is a colossal behemoth, scales the color of obsidian etched with star-silver runes. Its body is bound by chains wrought from meteoric iron and root-runed adamantine that sink into the world’s crust like roots. The creature moves with a patient, ancient patience, each breath a furnace-fume of primordial power. Eyes like dead galaxies burn with the cold light of a world-sleeping deity, and its maw spills a rust-red ichor that smells faintly of iron and stone. Its presence warps the air, bending sound and light as if the world itself trembles at the sight of its chained form.
Behavior & Origins
Long before civilizations rose, Qarathul was a god-beast of unknowable appetite and cosmic longevity. It was bound beneath the world’s crust by the Hand of Creation, a tangle of ancient pacts and iron chains forged by elder powers who feared its hunger for worlds. For eons it slumbered, the world above unknowing of the life-sucking, planet-shaking force below. The chains are not mere restraints; they are conduits, siphoning a slumbering god’s power to keep the world intact. When the seals weaken or the crust trembles, Qarathul’s gaze can pierce through stone and dream alike, and if ever freed, it would rend the crust apart to devour the stars themselves. It is content to sleep, to dream, and to hunger—so long as it remains bound. Adventurers who dare descend into its lair must contend with earthquakes, shifting caverns, and the whisper of a sleep-waking behemoth whose very chains sing of worlds that have fallen to ruin.
