Dragonmaw clan

The Dragonmaw clan is one of the orcish clans dating back to the time of the Rise of the Horde. Under the command of the shaman Zuluhed the Whacked, the Dragonmaws swore fealty to Blackhand the Destroyer with the other clans of the Horde upon Blackhand's ascension to Warchief. When Blackhand was assassinated by Orgrim Doomhammer, Zuluhed and the Dragonmaws maintained their fealty to Blackhand by pledging their loyalty to his sons, Rend and Maim, Chieftains of the Black Tooth Grin clan.

Activity on Azeroth
Manipulated by the Black Scourge, Deathwing the Destroyer, the Dragonmaws found an artifact of immense power known as the Demon Soul - created by Deathwing himself ten thousand years earlier, but forever forbidden from his grasp as the result of the spellwork of the other Aspects. Zuluhed entrusted the Demon Soul to a warrior/warlock named Nekros Skullcrusher, who used it to capture the Dragonqueen Alexstrasza - much to his surprise, and certainly to Alexstrasza's. The Dragonmaws used Alexstrasza's young to fight for the Horde - and fight they did, through much of the Second War. Operating out of the abandoned Wildhammer capital of Grim Batol, the Dragonmaws maintained their control over Alexstrasza and her flight after the Horde was defeated, using them to raid Alliance ports in the surrounding Wetlands.

The Kirin Tor high councillor Krasus - the humanoid form of the red dragon Korialstrasz, one of Alexstrasza's consorts - sent the mage Rhonin to free Alexstrasza from the Dragonmaws by somehow destroying the Demon Soul - which, using one of Deathwing's scales, he did. In their fury, Alexstrasza and her dragons tore Grim Batol apart and incinerated much of the Dragonmaw Clan, including Nekros, who was eaten. But some elements remain to this day in the Wetlands outside of Grim Batol. These forces are led by Nekros' son, Nek'rosh, who serves the self-styled Warchief of the Dark Horde, Rend Blackhand.

Activity in Outland
At some point during the Second War, Zuluhed and much of his clan returned to Draenor and survived the destruction that led to the creation of Outland. Now they are in the service of the Lord of Outland, Illidan Stormrage. Their attempts to subjugate dragons have continued — only this time, they are targeting a brood of nether drakes called the Netherwing. In what appears to be a repeat of their capture of Alexstrasza, the Dragonmaws have captured the matriarch of the Netherwing, the nether dragon Karynaku, and hold her prisoner in their fortress. Karynaku is held with a magical ball and chain, and only Zuluhed himself has the key.

In World of Warcraft


The rest of the Dragonmaw clan on Azeroth have established an encampment in Wetlands, led by Chieftain Nek'rosh Skullcrusher.

The Burning Crusade
Dragonmaw Fortress, where Zuluhed and much of the Dragonmaw clan resides, is located south of the Black Temple and east of the Netherwing Fields in Shadowmoon Valley. For some reason, certain members of the clan in this area can turn into Drakonids, this includes Zuluhed.

After the player has completed the entire questline associated with the Netherwing, their current situation is as follows: The leader of the Dragonmaw (Zuluhed) lies dead, along with masses of peons and other soldiers. Illidan is outraged because the Dragonmaw revered a person that was attempting to destroy the entire clan from within and failed to seize this betrayer despite the fact that he was at their very doorstep, chained in a powerful spell. Thus far we can only assume that Illidan has attempted to fully destroy the clan. As stated by the Netherwing "The Dragonmaw empire has come to an end."

Cataclysm
In World of Warcraft: Cataclysm it is revealed that Mor'ghor was able to survive Illidan's wrath and flee to Azeroth. Mor'ghor now styles himself as the Warchief of the Dragonmaw Clan using his fel orcs to keep their the regular orcs in control. When Horde forces arrived in the Twilight Highlands to negotiate with the clan, Mor'ghor killed the negotiator and decided to keep the player as a bargaining chip. However thanks to Zaela the player was able to escape and inform the Horde command of their tensions between the regular orcs and the fel orcs within in the clan. Using this information the Horde forces lay siege to Dragonmaw Port from the shore, and the Dragonmaw themselves take up arms against the fel orcs with supplies sent by the Horde fleet. The fight is eventually taken directly to Mor'ghor, and with the help of the Horde, he is disposed of. Zaela announces that a new Dragonmaw dawns with his death. After the Horde and Dragonmaw route out the remaining fel orcs Garrosh Hellscream arrives and meets with the new leader of the Dragonmaw Clan, Zaela and welcomes the clan into the Horde.

The Dragonmaw Clan will battle the Wildhammer clan in the Twilight Highlands battleground called the Twin Peaks.

It's unknown if they still have any sort of dragons, or if they have reconciled with the Red dragonflight -- although a number of Alliance quests in Twilight Highlands insinuate that they use Black Dragons. Horde-side quests reveal that the Dragonmaw hold a drake-enslaving artifact called the Demon Chain, an item that once held the Dragon Soul and still carries a portion of its power. The ability to cow and ride the black drakes--who are shown to be resentful of this--is preserved when the player retrieves the Demon Chain. The quest chain concludes by stating that the Dragonmaw's new black dragon air support will be a powerful addition to the Horde.

Origin of the name
It is unknown exactly what prompted the orcs to name their clan "Dragonmaw". It is apparent from Rise of the Horde that their name had been such for many years - long before the orcs encountered anything resembling dragons, the dragons being native to Azeroth. This may mean that there are or were dragons native to Draenor, or at the very least they existed in the form of mythological creatures in orcish culture - which may indicate that the Titans came to Draenor as well, which in turn indicates that the "reborn" Azeroth, freed from the Old Gods (and the Dragon Aspects), predates Draenor. It is also possible that something similar to a proto-drake existed on Draenor at some point. The Bladewing Bloodletters and the Vilewing Chimaeras may be such a creature.

It is possible however, that it is Blizzard's mistake originating in much different lore in times of Warcraft I and II, and many retcons that happened after. Dragonmaws might have simply eluded their attention and now it's too late to remedy it.
