Ecology

Leech Swarm is a non-magical animal, occupying a real ecological niche — predator, scavenger, herbivore, or pack member. It is most often found in swamp regions. It is medium-sized, which shapes how it hunts, hides, or fights.

Behaviour

Leech Swarm is driven by instinct — territory, hunger, fear, mating. Its alignment varies by individual or is irrelevant — it acts on instinct, drive, or whoever commands it. It is largely instinct-driven; complex strategy is the work of whoever (or whatever) commands it.

Origin

Leech Swarm is introduced in Kobold Press's Tome of Beasts 2 (2020). Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
