Ecology

Lacuna 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 ruins regions. It is medium-sized, which shapes how it hunts, hides, or fights.

Behaviour

Lacuna 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.

Origin

Lacuna is introduced in MCDM's Flee, Mortals! (2023). 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.
