Ecology

Brain Coral is an outsider to the natural order, often associated with the Far Realm or other planes whose laws differ from this world. It is most often found in underwater regions. It is huge-sized, which shapes how it hunts, hides, or fights.

Behaviour

Brain Coral is cold and inhuman in its goals; it does not think the way mortals think. Its Neutral 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

Brain Coral is introduced in Kobold Press's Tome of Beasts 3 (2022). Aberrations leak from the Far Realm or older creations that predate the gods, where the laws of reality differ. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
