The Siren: Shoshwana
An alien being reminiscent of an elf and a fish
The siren was ensnared and taken from her pod by pirates (their ears stoppered with wax). She was sold to the carnival for a large sum of money where she was put through strange abuses. Rescued by the party, she has begun to display concern for their well-being.
Odric has spent a lot of time with her, and from her learned a lot about her people. She has also provided her name: Shoshwana.
