Against the Legion

The Burning Legion has proven its capacity to corrupt mortal souls time and again. If I'm to entrust you with the knowledge you seek, I must have proof of your allegiance. A demoness known as Sathal has eluded me for a long time as she's gifted with an incorporeal form. She watches over the wrath priestesses as they do her bidding at Forge Base: Gehenna. Slay one of her minions and spill her blood on the ground. This affront should cause Sathal to materialize temporarily. Slay her while you can.
