In ancient China, a clever torturer created an elixir that paralyzes victims' limbs, heightening their nerve endings. The elixir, kept in a jade skull, can evoke a range of sensations, from pleasure to agony.

The skull remains hidden within an imperial seal, its curse spreading misfortune to anyone who possesses it.
