The Netherwing Ally is the cutest little dragon ally anyone could have!
The Netherwing Ally is summoned by the use of a couple different trinkets. The trinkets are different, but both call forth a Netherwing Ally to fight at your side. Both dragons look the same. They last around 30 seconds and the trinket has a 10 minute cooldown.
The first trinket is the Captain’s Badge. It is a reward from the quest Stand Tall, Captain! in Shadowmoon Valley. The second trinket is the Commander’s Badge. It is a reward from the quest Hail, Commander! in Shadowmoon Valley.
