Not far north from King’s Landing is an enormous lake, known simply as God’s Eye. And on the northern shores of the lake sit Harrenhal, a massive castle made totally from black stone. Harrenhal is the biggest castle in Westeros; an entire army can fit into the great hall. The castle was built by Harren the Black, who boasted that it was impregnable – Targaryen dragons proved that claim false, burning him to a crisp despite Harren being safely ensconced in his massive castle. Over the years, the castle has changed hands several times and has earned a rather sinister reputation for being cursed as past owners and their Houses often seem to experience a bad series of events, often leading to mysterious and inexplicable deaths.
