I built his fleet and did his work, dutiful as a younger brother should be to an elder, as Renly should be to me. And what was Robert's thanks? He names me Lord of Dragonstone, and gives Storm's End and its incomes to Renly. Storm's End belonged to House Baratheon for three hundred years; by rights it should have passed to me when Robert took the Iron Throne."
It was an old grievance, deeply felt, and never more so than now. Here was the heart of his lord's weakness; for Dragonstone, old and strong though it was, commanded the allegiance of only a handful of lesser lords, whose stony island holdings were too thinly peopled to yield up the men that Stannis needed. Even with the sellswords he had brought across the narrow sea from the Free Cities of Myr and Lys, the host camped outside his walls was far too small to bring down the power of House Lannister.
