Ecology

Arcanaloth* 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 planar regions. It is medium-sized, which shapes how it hunts, hides, or fights.

Behaviour

Arcanaloth* 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

Arcanaloth* is codified in the 5.5e Monster Manual. 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.
