Devouring Darkness

Devouring Darkness is a voidwraith vignette that spawns in Candle Rock in Highmountain after interacting with the circle of Kobold Candles. Per Deal With It Personally, it used to be held captive by Wardens.

Background
Despite being a mere vignette, legends have it that the Devouring Darkness is what kobold candles are supposed to protect against...

Notable loot

 * Void Slippers

Objective of
Needs to be summoned and killed for Deal With It Personally and WANTED: Devouring Darkness.

Speculation

 * An entity called The Darkness appears in the Kobolds & Catacombs expansion for Hearthstone. Due to its connection to snuffing out candles, The Darkness may be intended to be the same creature as the Devouring Darkness.
 * Uul'gyneth, who has the title of The Darkness, has the same role to the Highmountain tauren that the Devouring Darkness has to the Bluewax kobolds. They may or may not be related.
