Ecology

Elder Brain 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 underground regions. It is large-sized, which shapes how it hunts, hides, or fights. As a legendary creature, it is rare in the world and likely the only specimen of its kind in the local region.

Behaviour

Elder Brain is cold and inhuman in its goals; it does not think the way mortals think. Its alignment varies by individual or is irrelevant — it acts on instinct, drive, or whoever commands it. It is intelligent enough to plan, scheme, or remember. Spellcasting expands its repertoire well beyond what its physical stat block alone suggests.

Origin

Elder Brain is reprinted in Monsters of the Multiverse and expanded in Volo's Guide to Monsters. 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.
