Ecology

Snake swarms are unusual; most snakes are solitary or paired. Swarms form in shared birthing nests, hibernation pits, or near food bonanzas like rodent infestations. Once the trigger passes, the snakes disperse. Persistent swarms indicate a magical cause, often a hag's nest, a yuan-ti shrine, or a druidic ward. The snakes within the swarm vary by region but all share the same venomous instinct, attacking warm-blooded intruders with coordinated strikes.

Behaviour

Within the swarm, snakes do not communicate but respond to the same scent and movement cues, creating apparent coordination. They strike in waves, each snake getting one bite before retreating to refangle. Disturbed swarms hiss as a chorus, audible from a distance. They prefer cool stones near sun-warmed water. Cold weather scatters them into individual hibernation. Some swarms travel with their mother snake, a far larger specimen.

Origin

Yuan-ti legend speaks of the first snake-god scattering its essence into a thousand small kin to populate the world. Druids credit the snake-mother of the deep marshes. Whatever the source, swarms remind communities that the wilderness is not a backdrop but an active force. Villages that desecrate snake nests often suffer mysterious illnesses for generations afterward, a folk warning that endures.
