Deathbringer Volar

Deathbringer Volar is a character that appears in the VIGILANT mod. You fight him before you fight Laza of Order for the second time.

He is the right hand of Molag Bal, even though he appears once in the story. Twice if you picked Molag Bal's ending.

In other fiction
Deathbringer Volar appears as an antagonist in Cheafpic's Morgoth Bauglir playthrough. Where he dies three times. He cannot truly die as he is a Daedra. In the story, he is leading the attack on Weye in the First Battle of Weye and the Defense of Sacremor.

He is just as strong as Laza of Order but weaker than Mairon/Sauron and Gothmog in his first and second reincarnations.

In his third reincarnation, he threw Mairon around like a ragdoll which shows his true strength. He was able to manipulate the Thu'um just like Gothmog. The real reason he was so weak was because he was only testing them.
