Tarkoth Broadblade

Sir Tarkoth Broadblade was a bronze-scaled Dragonborn Paladin of Bahamut. He was part of the adventuring company called the Sword Watch. When the Sword Watch vanished, Tarkoth vanished with them. Later, an Undead Dragonborn calling himself Tarkoth and claiming to be one of the Reborn traveled with Elswara Wellheart, but it was proven that he was not who he said he was. This impostor was revealed to be Shadarak Mithranak , the Dragonborn Paladin who was part of the Argent Circle. This means that Tarkoth must be dead, which is likely a kinder fate than to be a fallen death knight.
