Nicknames and Pseudonyms that a Dragon might use.

The campaign I am currently running is set in a vaguely early Renaissance setting and I'm planning on having the players meet an influential Patron of the Arts in the City State that they're traveling to.

Unbeknownst to anyone in the city the woman is actually an ancient Green Dragon in disguise using her position to collect and manipulate interesting people. Obviously the players are on a collision course with her schemes and plots, but I'd like for the players to hear something of her fame long before they meet her.

So what I'd like to do is give her an interesting and memorable nickname among her "followers" that the players might rub shoulders with on their journey.

"The Green Lady" seems a bit too on the nose and I'm stuck trying to find something memorable but not obvious.
