Ecology

Elder Brain Dragon 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 gargantuan-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 Dragon is cold and inhuman in its goals; it does not think the way mortals think. Its Lawful 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

Elder Brain Dragon is expanded in Fizban's Treasury of Dragons. 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.
