Beric Dondarrion

Lord Beric Dondarrion was a Lord of Blackhaven and head of House Dondarrion, before becoming the leader of the Brotherhood Without Banners. During a visit to King's Landing, he was ordered by Hand of the King Eddard Stark to track down and execute Ser Gregor Clegane following reports of him pillaging the Riverlands. During the Battle of Mummers Ford, he was killed by Clegane, but brought back to life by Thoros of Myr through his prayers to R'hllor. The survivors of the battle went on to form the Brotherhood Without Banners, led by Beric, to protect the smallfolk and fight the Lannister forces. During his time leading the Brotherhood, he was killed a further five times, including by Gregor's brother, Sandor Clegane, but brought back each time by Thoros. He eventually turned his attention to the looming threat Beyond the Wall, and lead his remaining forces to Eastwatch-by-the-sea. During the ensuing Wight Hunt, Thoros of Myr was killed, leaving Beric without a means to return should he die a seventh time. Beric was finally killed permanently during the Fall of Winterfell, whilst holding off wights to allow the sheltering women and children to escape the doomed castle.
