Greyshield
Escudo Gris
Greyshield belongs to the cluster known as the Shield Islands, the string of islets that guards the mouth of the Mander just before the river opens into the Reach. Within its bounds stands Grimston, seat of House Grimm, and that position has turned the island into a natural chokepoint for traders and ironborn raiders alike.
