Tears of Lys
The tears of Lys is a rare and expensive poison, made by the alchemists of Lys. It is clear, tasteless, odorless, and leaves no trace. When dissolved into liquids and drunk, the poison eats away the bowels and belly of the victim, and appears to be a sickness of those parts. It is unknown if the poison has a connection with the Weeping Lady of Lys.
At the end of 54 AC, Cassella Staunton, Septa Maryam, Alayne Royce, Lianna Velaryon, Samantha Stokeworth, and Maester Culiper died on Dragonstone. The castle closed its gates as quarantine to protect the island from an epidemic, but Lord Rego Draz recognized the symptoms as those of the tears of Lys. The poisoner was Androw Farman, jealous of his wife Rhaena Targaryen's friendships with her ladies.
