Dragonmaw Gates

Dragonmaw Gates are a set of grandiose portals that block the winding path leading up to Grim Batol. The gates are guarded by several different types of dragonkin of the red dragonflight, as well as the powerful drake Axtroz. It is possible to pass through the gates and survive, but past the last gate, the area just below the mountain is completely deserted. It is possible this area will contain a red dragon later in the game's development.

In Cataclysm
The Dragonmaw Gates now open into the Twilight Highlands and are no longer part of the Wetlands.
