Adventure Hook

A haunted mirror hires the hero to recover its missing reflection before midnight, promising one truthful answer in return.

Read-Aloud Opening

“The antique mirror clears its silver throat. Your reflection is gone. In its place stands an empty ballroom, ankle-deep in dust, with one set of fresh footprints leading away from the glass. 'I can pay,' the mirror whispers. 'Bring me myself before midnight.'”

DM Brief

  • Design every obstacle around the solo hero's strengths. If they are martial, make clues physical; if magical, let spells reveal emotional truths.
  • Use sidekick-style help without stealing spotlight: the mirror can speak, warn, and panic, but cannot solve scenes.
  • Keep combat small and dramatic. One enemy with a motive is better than a room full of attacks against a solo PC.

30-Minute Pacing Notes

  • 0:00–4:00 ask the player why their hero needs one truthful answer; that answer becomes the reward.
  • 4:00–13:00 Scene 1 establishes the mirror as anxious, useful, and slightly vain.
  • 13:00–22:00 Scene 2 is one focused investigation challenge with two clues, not a maze.
  • 22:00–30:00 Scene 3 is a duel, bargain, or rescue with the reflection thief.

Clip-Worthy Moments

  • The hero sees a reflection doing something they would never admit wanting to do.
  • The mirror gives terrible tactical advice in an aristocratic whisper.
  • A ballroom dance happens with only one visible dancer and one stolen shadow.
  • The truthful answer appears written backward in silver breath on the glass.

Scene 1 — The Empty Reflection

8 minutes

“Candles around the mirror burn with blue flames. When you move, the glass shows only the room behind you. Something on the other side has left with your shape.”

Goal: Give the solo player agency and two paths into the mirror-world.

What Happens

  • • The mirror can open a palm-sized window into its ballroom if fed a drop of ink, blood, or wine.
  • • A DC 12 Arcana check identifies the thief as a Reflection Jack, a fey that steals unused possibilities.
  • • The missing reflection left three backward words on the frame: dance, debt, door.

Checks

  • • Investigation DC 11 finds a cold handprint where the reflection climbed out.
  • • Performance or History DC 12 recalls the old etiquette: every mirror ballroom opens with a bow.
Fail forward: On failure, the hero enters the mirror-world anyway, but the Jack learns one fear from their reflection and uses it in Scene 3.

Scene 2 — Ballroom of Almosts

10 minutes

“Inside the glass, the ballroom is full of almost-people: almost you as a knight, almost you as a thief, almost you walking away from every hard choice.”

Goal: Turn investigation into character spotlight.

What Happens

  • • Two clues are required: the Jack hides behind music with no musician, and the stolen reflection refuses to step in dust.
  • • The almost-people ask tempting questions but cannot attack unless the hero attacks first.
  • • The mirror can reflect one object from the real room into the ballroom if the hero describes it clearly.

Checks

  • • Insight DC 12 tells which almost-person is lying about being the real reflection.
  • • Acrobatics or Performance DC 12 completes a dance step that reveals the hidden door behind the music.
Fail forward: If the hero fails twice, they find the door but arrive off-balance; the Jack acts first in Scene 3.

Scene 3 — The Reflection Jack

12 minutes

“A figure wearing your face lounges on a throne of cracked hand mirrors. It smiles with your smile and says, 'You weren't using every version of yourself. I borrowed one.'”

Goal: Resolve with a duel, bargain, or self-defining choice.

What Happens

  • • The Jack wants to keep the heroic reflection because it is tired of being nobody's favorite possibility.
  • • A bargain works if the hero names one path they reject and one path they choose; the unwanted almost-self becomes the Jack's new face.
  • • A fight ends when the Jack drops to 0 hit points or when the hero uses an action to touch the stolen reflection and speak their name.

Checks

  • • Persuasion DC 13 convinces the Jack to trade faces without combat.
  • • Wisdom save DC 12 resists the Jack's stolen fear from Scene 1.
Fail forward: If the Jack wins, the hero escapes with their reflection slightly delayed by one heartbeat and a future hook: the Jack is now free in the real world.

Stat Blocks

Reflection Jack

AC 14 · HP 24 · Speed 30 ft.

Traits

  • • Mirror Step: once per round, the Jack can move 10 feet between reflective surfaces without provoking opportunity attacks.
  • • Borrowed Face: it has advantage on Deception checks against creatures whose reflection it has seen.

Actions

  • • Silver Pin: +5 to hit, reach 5 ft., 6 piercing damage.
  • • Almost You, recharge 5–6: DC 12 Wisdom save or the target has disadvantage on its next attack or ability check as an almost-self distracts them.

Almost-Person

AC 11 · HP 7 · Speed 30 ft.

Traits

  • • Unfinished: disappears if asked a sincere question it cannot answer.
  • • Glass Bones: vulnerable to thunder damage.

Actions

  • • Soft Accusation: +3 to hit, reach 5 ft., 3 psychic damage.

Rewards

  • The mirror answers one personal question truthfully, though the answer may be symbolic.
  • The hero gains a pocket mirror that grants advantage on one Insight check per long rest if they look themselves in the eye first.

Scaling Notes

  • For a fragile solo character, reduce the Jack to 18 hit points and make the Almost-People purely social obstacles.
  • For a powerful solo character, give the Jack one Almost-Person ally and let Mirror Step move 20 feet.
