Called to action by the red dragonflight in the Twilight Highlands, players will be charged with putting a decisive end to the foul machinations developing within the level-85, 5-player dungeon of Grim Batol. The ferocity of the enemies within should not be underestimated, and with the assistance of brave Red Drakes and a handful of explosives, players can thin the ranks of Grim Batol's occupiers through bombing flights into the ruined city's corridors. Regardless of how successful these attacks might be, General Umbris will not allow his army to fall so quickly. In the end, adventurers will be left to their own devices, venturing into the darkest recesses of the dwarven fortress, where a nightmarish enemy is taking shape. Will you be able to uncover Grim Batol's secrets and emerge unscathed, or will your destiny be sealed within this tortured city, like so many brave heroes before you?
