Serinar is located in the Maw of Neltharion. A Burning Depths Necrolyte lies dead on the ground to his side. Players are sent to aid him in defending the Obsidian Dragonshrine. For a member of the black dragonflight he is rather friendly, expressing gratitude towards the player 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 player as an "effective tool."
