The Story

The Assault of the Old Gods' Minions
After the legion's defeat and Sargeras' imprisonment, the heroes of Azeroth believed they were triumphant but they were wrong, the battle has scarred Azeroth greatly which granted N'Zoth the old god and his minions the chance to pour from every corner of the Eastern Kingdoms. Under the command of General Xi're'q; The old gods' forces ravaged one mortal foothold after another causing the heroes of Azeroth to flee into the Arathi Highlands for shelter.

The Arathi Conflict
The human Thaelyn was capable of rallying the refugees under one banner, together they ventured into Stromgarde Keep and took it for their own. Thaelyn was hoping to have his last stand with the old gods' forces upon this ground but he was kidnapped by Behamahl and was taken as a prisoner in the Hellwrath Vanguard's flagship, the Hellwrath Vanguard being a surviving demonic force from Antorus who reformed their ranks and ventured back to Azeroth for the sole purpose of having their revenge upon them.

The vanguard, now having Lord Thaelyn with them were certain to attack Stromgarde Keep, they lured the mortals' main strikeforce out of the keep using Gargoth while their main attack team would attack the defenseless city.

The attack seemed successful at the beginning until Feludus, a dwarf who had been loyal to the old gods' forces all along has allowed the forces of N'Zoth inside the keep to attack both the demons and the heroes. The demons were forced to retreat in defeat back to their flagship while the mortal survivors of Azeroth escaped Stromgarde and eventually into Tirsifal Glades.
