Adventure Guide Entry

The in-game Adventure Guide text for The Blast Furnace encounter in Blackrock Foundry.

The Blackrock clan's unique ability to smelt the black ore, a substance so dense that ordinary flame does not even soften it, has always been their most closely-guarded secret. Deep within the Foundry, their furnace contains a primal force as old as Draenor itself, raging within the confines of its prison as it emanates a preternatural heat.
