Nazerian

"What one plain orc can do alone is limited... but I, am no plain orc... and I am not alone..."

Naz'groth was a orc warlock in service of Gul'dan and part of the Shadow Council during the Rise of the Horde. He was sent to Auchindoun alongside Vorpil Ribcleaver and Blackheart the Inciter, and was subsequently killed by Murmur when the primordial essence was summoned onto Draenor.

Rise of the Horde
Naz'groth was originally part of the Shadowmoon Clan just like his master, Gul'dan. Naz'groth worked alongside the elements as a shaman for some time before Gul'dan introduced the concept of warlock practices, and subsequently Naz'groth almost immediately dropped the elements and settled for the use of fel magic over them. Following this, Naz'groth was accepted into the Shadow Council due to his prowess over wielding the tainted energies he now mastered. He performed so well at his vile spellcraft, he came into notice by Kil'jaeden himself. The eredar knew Naz'groth had the potential to become a force of immeasurable destruction, and therefore personally gifted him with one of his terrorfiends as a minion.

When the Horde set out to massacre the draenei of their homeworld, Naz'groth gleefully accepted the task, he and his ered'ruin ally alike laying waste to hundreds, if not thousands of draenei lives and claiming their souls as a bounty. When Vorpil Ribcleaver and Blackheart the Inciter were sent to plunder Auchindoun, Naz'groth and his minion were sent to follow in suit and aid in leading the Cabal, a sub-group of the Shadow Council.

Beyond the Dark Portal
When Vorpil and Blackheart attempted to summon Murmur into Auchindoun, both Naz'groth and his minion advised against it, an uncharacteristic rationality behind their words. Naz'groth claimed that the being would be too powerful to control, and would only serve to tear Draenor apart at the behest of itself. Unwilling to listen to the warlock's warnings, Vorpil and Blackheart continued their rituals, and did eventually manage to summon Murmur into Auchindoun. However, the primordial essence of sound shattered Auchindoun into a ruin of its former self, and while Vorpil and Blackheart survived the blast, Naz'groth and his terrorfiend were both killed by the destruction razed by Murmur's powerful induction onto Draenor.

While the ered'ruin was simply banished back to the Twisting Nether, Naz'groth's body was torn and scattered to the winds of Talador, his ethereal spirit thrown from the very plane of existence. From there, he met a horrible and devilishly ironic fate, as all the souls that he had once imprisoned and consumed came back to haunt him, tearing his own apart in their final acts of transcendent vengeance.

Personality
While bearing the typical nefarious persona of a warlock, Naz'groth still listened to reason and took order into consideration when he went about inflicting his wrath. He had an insatiable taste for chaos despite this, and his two warring personalities constantly clashed with one another. This inevitably led to his demise at the hands of Murmur's omnipotence.
