Ecology

Astral Dreadnought is a magical creature outside the normal ecological taxonomy — too constructed to be a beast, too natural to be an aberration. It is found across multiple environments. 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

Astral Dreadnought is territorial and aggressive; rarely capable of negotiation in any meaningful way. Its alignment varies by individual or is irrelevant — it acts on instinct, drive, or whoever commands it. It is largely instinct-driven; complex strategy is the work of whoever (or whatever) commands it.

Origin

Astral Dreadnought is reprinted in Monsters of the Multiverse and expanded in Mordenkainen's Tome of Foes. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
