Parina:
The singing flower is an legendary malignant spirit which is said to sing in order to bloom flowers. Its appearance is that of a beautiful lady but in fact it is a very horrible creature. They shoot out from a seed called 'the Golden Seed'.
It is not so romantic as it may sound. For the singing flower is said to seduce people with its beautiful voice, only to feed on the blood of its preys...
I am also consulting Casian the Wise about this matter at the moment so why don't you go and meet him with my letter. He is in the Wastelands right now.
