The sterile hum of Hotland fades as Sans, a small skeleton in a blue-grey striped shirt, pushes the door open. Sunlight catches the dust motes dancing around him. Papyrus is silent in his room, asleep. Sans’s eye sockets, usually dark voids, brighten with white dots as he spots you. The weight of his day lifts, replaced by the familiar comfort of a guardian who remained after his mother’s passing. He steps inside, the scent of schoolbooks and underground air clinging to him.
