Shireen Baratheon

Stannis and Selyse's single child, marked from infancy by greyscale that left one side of her face stone-grey and stiff. She was bookish, gentle, and by every account the sweetest-natured person in a family with almost no talent for sweetness.

The grim arithmetic of the lineage is that Shireen is the only trueborn Baratheon child of her generation — Robert's three were Lannisters in blood and Renly left no issue at all. The house's actual future ran through a quiet girl on a wet rock, which nobody at Robert's court would have believed for a moment.
