Ecology
Bone Swarm is a creature that has crossed the threshold of death; its continued presence is itself a violation of natural law. It is most often found in any regions. It is large-sized, which shapes how it hunts, hides, or fights.
Behaviour
Bone Swarm is haunted by what it was in life; its goals echo old grievances or the will of the necromancer who raised it. Its Chaotic Evil alignment shapes how it engages with the world — predictable in tendency, even when unpredictable in detail. It is intelligent enough to plan, scheme, or remember.
Origin
Bone Swarm is introduced in Kobold Press's Tome of Beasts 1 (2016). Undead are the wounds the Negative Plane leaves on the mortal world — every undead has a death story behind it. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
