Derek Blackthorn

Count Derek Blackthorn of Cheydinhal, claiming to be High King Derek I of Cyrodiil, was an Imperial claimant of the Kingdom of Cyrodiil in the Second Era. Originally serving as Count of Cheydinhal under High King Titus Vallerion, Derek, along with five other vassals, openly claimed the ruby throne for themselves. A six year total war broke out which came to be known as the War of the Seven, which saw Derek as a major player and near victor.
