Ecology

Merrenoloth is a creature of the Lower Planes, present in the mortal world via summoning, banishment-failure, or a planar breach. It is most often found in coastal regions. It is medium-sized, which shapes how it hunts, hides, or fights.

Behaviour

Merrenoloth is cruel and patient, willing to take centuries to repay an insult. 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

Merrenoloth is reprinted in Monsters of the Multiverse and expanded in Mordenkainen's Tome of Foes. Fiends originate in the Lower Planes — the Nine Hells, the Abyss, or further hells beyond — bound to whatever cosmic hierarchy that plane enforces. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
