Ecology
Leviathan is a being of one of the inner planes, summoned, escaped, or birthed where planar boundaries thin. It is most often found in coastal 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
Leviathan is simple in motivation but immense in reach — fire wants to burn, water wants to flow. 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
Leviathan is reprinted in Monsters of the Multiverse and expanded in Mordenkainen's Tome of Foes. Elementals come from the inner planes — the Plane of Fire, Water, Earth, Air, or the para-elemental borders. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
