A Proposal.

"So it was that Dor Moshash the geometer king came before the she-worm Brigadora of Garm: for she had taken the city and ruled it wisely as queen. 

And the king said to her: coiling worm, who lights the sky with her fire at night. Make me your man, and yours will be the secrets of the curves and the lines and the motions of the stars. 

And the dragon answered. You will be my husband and rule this city by my side. But keep those secrets and guard them well. For I already have the secrets of the hunt and the flame and the motions of animals, and I fear what I could become."
