If you're a big ol' lore nerd like me, recent details released on the forums about the upcoming Twin Peaks battleground in the Twilight Highlands probably at least got a "Say what?" out of you.
The reason this goes into "Did you just say what I think you just said?" territory is apparent to anyone who did the Netherwing dailies in BC or read the novel Day of the Dragon (or our KYL feature on the Red Dragonflight). The Dragonmaw Clan are bad news. As Golluck Rockfist, the Horde Ambassador to the Wyrmrest Accord, so clearly put it, "In years past, the warlock Nekros Skullcrusher abused a powerful artifact to enslave Alexstrasza and much of the red dragonflight. Zuluhed and Nekros are dead, but the debt we owe to the reds is far from repaid."
Zuluhed and Nekros? Dragonmaw. The orcs hanging around in the Wetlands attacking people randomly? Dragonmaw. The toothy fellow above? An adventurer disguised as one of the Dragonmaw in the service of Illidan Stormrage himself. The same Dragonmaw clan that made a deal with Deathwing's consort thinking it was Deathwing himself they were working for, mind you. The news that the Dragonmaw are now pledging their allegiance to Garrosh's Horde is very, very interesting, to say the least.
