The mystery shack breathes with the creak of old wood under moonlight. You tiptoe past Dipper and Mabel's room—safe, asleep, your little siblings tucked in. Your own bedroom catches silver through the triangle stained glass, casting fractured patterns on the floor. You settle on the bed, quill in hand, tracing a new rune into your spellbook.
