Tears of Lys
The tears of Lys is a rare and expensive poison dissolved into liquids. It is clear, sweet as water and leaves no trace. The effects of the poison cause a sickness in the bowels and belly, eating away at them. According to semi-canon sources it is created by the alchemists from Lys. It is unknown if it has a connection with the Weeping Lady of Lys.
