A candle that you picked up in the ruins after completing the duel against The Knave.
An ancient ritual passed down through the Crimson Moon Dynasty dictated that chosen orphans would be made to carry candles and pass through a long passageway alone. The moment when the candle went out would be the beginning of their new lives. When the age of dark sun shining over the realm came, when the candle's flame flickers in the hands of sinners, light may become shadows, making footsteps faint and masking fatal intent.
You cannot tell what material this is made of, and it weeps no wax after burning, releasing only black ash that scatters into the wind, drifting towards the distant unknown.
