Kaer Muire is the imposing, ancient stone fortress of Clan Drummond, carved deep into the vertical sea cliffs of southern Ard Skellig. Commanded by the notoriously stubborn Madman Lugos, the keep is famous for its heavily militarized, aggressive atmosphere. The internal architecture features vast stone feasting halls adorned with stolen shields, dark barracks, and a sheer drop down to the jagged coastal rocks below, embodying the fierce, uncompromising spirit of Skellige’s most warlike clan.
