Y'Syska was an evil sorceress.
Her collection of gems and minerals was without compare. At one time she owned the Crocodile's Tear, which she protected by hiding it in the Miznia jungle. Survivors of the jungle came back to report that the Crocodile's Tear rested on a large idol.
It is rumored that the same peasant who recovered the Coconut of Quendor also successfully stole the Crocodile's Tear, but this is not a confirmed report. Y'Syska's final fate in unknown.
