The Forge of Corruption[[:File:|[, ]]] in Mardum is presumably where Overseer Brutarg forges weapons for the Burning Legion forces in the zone, considering the enormous forge and hammer there. While most of the area is flat and pock-marked with fel pools, a singular cave[[:File:|[, ]]] can be found near the border with the Doom Fortress. Little but a small skirmish and fel equipment is found within.
