Ecology

Flesh Mournling is a creature that has crossed the threshold of death; its continued presence is itself a violation of natural law. It is most often found in ruins regions. It is large-sized, which shapes how it hunts, hides, or fights.

Behaviour

Flesh Mournling is haunted by what it was in life; its goals echo old grievances or the will of the necromancer who raised it. 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

Flesh Mournling is introduced in MCDM's Flee, Mortals! (2023). Undead are the wounds the Negative Plane leaves on the mortal world — every undead has a death story behind it. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
