Hammerhorn is the seat of the main line of House Goodbrother in the Iron Islands. The castle lies in the Hardstone Hills on Great Wyk. Its maester is Murenmure.[2]


A large square castle, Hammerhorn has spiky iron battlements. The stones used for its construction were quarried from the cliff behind it. Below its main entrance lie the openings to the mines and caves within which toil the smallfolk in service to House Goodbrother. Hammerhorn's hall is dank and drafty.[2]
