Nether-Stalker Nauthis wants you to slay 12 Wrathbringers at Forge Base: Gehenna, north of the Stormspire.
Brave acts of industrial sabotage will only get us so far, [player]. Just as Forge Base: Oblivion serves as an assembly site for Fel Reavers, Forge Base: Gehenna serves as a staging ground for their army as it is where the majority of the Legion's teleportation devices are located.
I want you to go in there and put a dent in their numbers. They must have a full regiment of wrathbringers by now and we just can't allow that.
