Adventure Hook
At a candlelit inn room with one tall mirror, the hero's reflection is dragged into a bargain room by a glass hag. This ready-to-run adventure starts at the problem, gives the DM two concrete clues, and resolves in three scenes without extra prep.
Read-Aloud Opening
“Your reflection blinks one second late. It presses both palms to the inside of the glass and mouths help while a black velvet room appears behind its shoulder.”
DM Brief
- Target query: solo one shot dnd for tiktok. Start with the premise and avoid lore homework.
- Core truth: the reflection is a possible future, and saving it means choosing one risk worth taking. Put backward writing on the mirror that says DO NOT LET ME AGREE and a keyhole that appears only when the hero admits one fear aloud in play early so the table always has a next action.
- Primary NPC: the hero's own frightened future reflection. They point toward danger, model the tone, and keep the pace moving.
30-Minute Pacing Notes
