Ghaston Grey
Rocagrís
Ghaston Grey is a tiny, rocky island lost in the Sea of Dorne, crowned by a ruined castle that Westeros keeps for prisoners no one wants to see again.
It isn't a fortress anyone visits: it's a one-way destination, the place someone is sent when the goal is to make them disappear without having to kill them.
Chapter 1
A prison in the sea
Books only
Off the coast of Dorne, out in the Sea of Dorne, a crag rises topped by the remains of a castle nobody bothers to repair anymore. Little grows there, and no one lives on the rock by choice.
Westeros uses those ruins as a prison for criminals judged too dangerous for an ordinary dungeon. Men are sent to Ghaston Grey to waste away, and those who know the place count it among the worst anyone can be condemned to.
Chapter 2
The conspirators of Sunspear
Books only
At Sunspear, the castellan Ser Manfrey Martell tells Princess Arianne what has become of three of her allies in the plot to crown Myrcella Baratheon queen: Ser Andrey Dalt, Lady Sylva Santagar, and Garin.
Doran Martell — Arianne's own father — has had all three sent to Ghaston Grey. The news lands hard, because Ghaston Grey is the prison island Dorne only speaks of in a low voice.
