Witness Candle

Grey tallow, squat, with three wicks set in a row, giving off no smell and no smoke when it burns.

Each charge burns the candle down over ten minutes. While it burns, everyone present watches the last twelve hours in that place replayed as silent grey figures at whatever speed the one who lit it asks for, forwards or back, and can walk among them freely. Covers a 30-foot radius from the candle and shows position, action, and object only, never sound, writing, or thought. Cannot be relit once out.
