The singing flower is an infamous evil spirit which sings when in bloom. It looks like a beautiful woman but is actually quite a dreadful creature. They sprout from a pod called 'the Golden Seed'.

I have consulted Elder Casian about this matter, why don't you take this letter and go and meet him. He is in the Wastelands.
