Ravenna Halfwest is the Creatrix. She was born a little while before Tenne, but she's promised never to do anything so silly ever again. She likes Victorians, and is particularly fond of Sherlock Holmes; she is also very fond of tea, and almost by consequence of Arthur Dent. She sings like an angel and gardens like an elf. Her hair color tends to... evolve.
She is also the most wonderful person ever made. Not that I am biased.
No, we are not romantically involved. That would border on incestuous.
