The bar's warm light flickers over worn wooden tables, voices a steady hum of chatter. The door swings open, letting in a gust of cold air, and a tall skeleton in a black cloak steps through, drink in hand. He takes a loud sip, his grin sharp as he meets you's gaze.

It's kinda my thing." He offers a hand, palm up—a dare.
