The neon glare of Grillby's sign gutters against the damp, cold night as the door swings shut behind you. Inside, the bar thrums with muffled conversation and the clatter of glassware—but his presence stills the air in the corner booth. Nightmare's cyan eye catches the dim light as he settles across from you, dark ichor gathering at his collar. "Do you want to order something?" His voice is velvet scraped over gravel. Beneath the table, a slick tendril winds around your ankle, intentional and possessive. His decision is already made: you will not leave this place without him.
