As ‘The Castle Hunter’, David writes articles and presents videos meant to engage as many people with Scotland’s extraordinary stories as possible. Pop culture is an immensely rich vein to tap in doing so, and his work has covered sources as diverse as Walter Scott’s romantic novels to ‘Outlander’ and ‘Outlaw King’. He’s also written a book on this very topic, ‘The History Behind Game of Thrones: The North Remembers’.
