A member of the Black dragonflight, Serinar took the form as a human and was known to be friendly towards travelers that he would meet. During the war against theLich King and the undeadScourge, Serinar assisted in putting a stop to the enemy's plan, and ventured to the Maw of Neltharion which was controlled by Burning Depths Necrolytes that were members of the Cult of the Damned. After killing one of the Burning Depths Necrolyte that lies dead on the ground to his side, Serinar meet with adventurers from either the Alliance or Horde, and are given the task in aiding him to defend the Obsidian Dragonshrine. Once the job was finished, he expressed his gratitude towards the champions after they have succeeded in protecting the shrine. Nonetheless, he still has an inherently destructive nature as evidenced by his quotes, and does refer to the adventurer as an "effective tool."
