Vertvern and Cynthia are the subjects of a famous duet which Dandelion and Essi Daven sing by the fire at a camp in Dol Adalatte where the two are spending the evening along with Geralt. The first line of the ballad is said to begin: "These are not my first tears..."

The ballad is mentioned in the short story "Trochę poświęcenia" ("A Little Sacrifice").
