Guardian of her Gates. Hulderotica, #6

Hulngal is a mystic who spends her days running a decidedly niche curiosity shop that offers the kind of relics and services you don't buy with money. A shop with powerful clientele. So when her store bell rings not long before closing, she expects to add a bit of excitement to an otherwise dull evening. Until it turns out to be Marrowmont's most useless demon, the twice-fallen Avnas. But he's come to beg her to use the gates she commands to send him home to the pit.
So maybe she is in for an exciting evening after all. Because if she decides to grant his wish, the price is steep. And she'll make him pay it body and soul.
