Ecology

Gargantua 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 mountain regions. It is gargantuan-sized, which shapes how it hunts, hides, or fights.

Behaviour

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

Gargantua appears in published 5e bestiaries. 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.
