The official bestiary guide for Wrath of the Lich King has been updated. The latest addition is the Iron Dwarf, denizen of Northrend:

The Explorers' League has scoured the far corners of the world, seeking to uncover the truth behind the origins of the dwarves. Now it seems they may be one step closer to unlocking the secrets of the past.

The latest clues come from ancient dig sites within the Howling Fjord, where the iron dwarves were first encountered. Etched with runes of power - and with lightning pulsing beneath their thick, metallic skin - they may represent the missing link between the dwarves and the legendary titans of myth. Unfortunately the malevolent iron dwarves have openly defied the Explorers' League and seem intent on destroying any and all artifacts connecting them to the shadowed recesses of history.
