Si'Nassapherion or Si'Nassaspherion

She is the mother matron of all of Chrailis.
As an immense dragon, her wingspan is nearly a quarter of a mile. She is covered in thick emerald scales, each scale taking on a gemstone quality and having a slight translucence to them.
Her powers rival that of a god. Within and around Chrailis, she is often seen as a god, though she does not grant her followers any powers. However, she is extremely possessive of the city and its inhabitants, viewing them as part of her treasure.
She is extremely intolerant of any other form of draconian presence in her city. Even her children will not take dragon form within the city if Si'Nassa is present.
