Cassana Estermont

Lady Cassana of House Estermont married Steffon Baratheon and bore him three sons in Storm's End, that great grim fortress on the cliffs. She sailed with her husband on the errand to Volantis and drowned beside him in Shipbreaker Bay, close enough to shore that her children could watch it happen.

The record leaves her thinly drawn, as it so often does with the mothers of loud men. What can be said is that the three boys she raised turned out ferociously different from one another and ferociously stubborn all the same, and that they lost her far too early to know which parts of themselves were hers.
