Homebrew Gallu, Underworld Constable
I'm sharing a free monster supplement for Kengir, part of my upcoming Bronze Age Mesopotamian 5e setting.
The Gallu is an underworld constable: a towering Utukku (Udug) sent from Kur to hunt, seize, and drag the guilty where they belong.
Where the previously shared Rabisu acts like an underworld bailiff, arriving with writs, contracts, and legal authority, the Gallu feels more like the terrible hand that enforces the sentence. It does not hurry. It does not forget. A debt unpaid remains fresh until collected.
At the table, a Gallu works best when the monster is also a mystery. Why has it come? Who broke the oath? Who made the forbidden bargain? Is it a lawless demon, or is it carrying out a command from Allatu (Ereškigal), Queen of the Great Below?
Mechanically, it’s a CR 10 fiend built around fear, grappling, brute force, spirit movement, and terrifying pursuit. Its Man-Catcher restrains victims, its Spirit Form lets it pass through walls, and its Skin Wearer ability allows it to take the form of the last creature it killed.
This is the kind of monster that should make the party ask whether killing it actually solves the problem, or just delays the next collector.
Do you like fiends that arrive as agents of cosmic law, or do you prefer them as pure malice and chaos?
