She´s the very first draft of an idea that has been going on in my mind for some time, so I´m fully aware she´s very imperfect and primitive. And if you call her Medusa, I´ll send virtual Furies after you ;-)
Daphne doesn´t like getting old, therefore any kind of death, be it actual or symbolical, frightens her. Loving Phoebus means she´ll have to leave a lot of her 'ninph' self behind, and there´s the risk he won´t be with her forever. So, becoming a tree seems like an alternative - at first, and at a price.
I obviously based myself on the Greek myth of Apollo and Daphne, but I want to show my idea of what/who Daphne and Phoebus could be.
