Sharn Veltaris
Importance:
Garen's daughter, and the Veltaris who takes an interest in what Marik could be made into. She finds him after the hunt and presses him toward a dragon bond - a prince with a dragon, by her reckoning, being a hard thing to refuse. Marik's one real offer of help to Edwinn is a letter addressed to her, asking her to put House Veltaris between his brother's family and whatever is coming.
Since then
A prince they can argue with. A prince on a dragon they have to answer. Decide which one you would rather be.
