First Day at Spellhaven: A 5e Magic-School One-Shot Adventure for Small Groups

It is orientation day at Spellhaven Academy, and the great enchanted clock has begun to run backward. The academy's ancient prank-construct has malfunctioned - and its harmless mischief is turning deadly. First Day at Spellhaven is a complete, ready-to-run one-shot for fifth edition - a cozy magic-school adventure with real teeth. Your players are four misfit second-years handed the easiest job in the school: show a terrified new first-year around campus. Then the wards crack, the pranks turn dangerous, and the giggling paper creatures start pouring out of the walls. At the heart of it is Riffle the Rebound: a three-hundred-year-old construct of silver wire and enchanted parchment, built to challenge students with harmless mischief and slowly going out of his mind from the boredom of it. His binding is failing. His pranks are growing teeth. And the whole academy is folding itself into a funhouse with the safety rails coming loose. To save the school, your players will cross a collapsing great hall, outwit a possessed janitor wrapped in living mops, and decide the fate of a lonely construct who only ever wanted to teach.
