Season of Mastery: The Ahn’Qiraj War Effort Begins April 21

news.blizzard.com:

The great desert fortress of Ahn'Qiraj, long sealed behind the Scarab Wall, is home to the insectoid qiraji, a savage race set to mount an assault to devastate the continent of Kalimdor. But something far more sinister lurks behind Ahn'Qiraj's walls: the Old God C'Thun, an ancient entity whose pervasive evil had suffused Azeroth since time immemorial.

The next Content Update for WoW Classic Season of Mastery will be available worldwide on April 21, at 3:00 p.m. PDT. At that time, the Ahn’Qiraj War Effort will begin, and both factions must heed the call. Any hero brave enough to undertake the epic quest to become a Scarab Lord will be able to begin their journey.

Due to the faster release cadence of Season of Mastery, we’ve made some adjustments to the War Effort:

In addition, those who venture into the Temple of Ahn’Qiraj will now encounter the mysterious Prophecy of Chaos, which will allow those in good standing with the Brood of Nozdormu to undertake additional challenges within the Temple. C’thun has also been restored to his original, most horrific form; you can expect this nightmarish Old God to present a much greater challenge than his original WoW Classic incarnation.

If you’re not familiar with the Ahn’Qiraj War Effort and how it all works, read on!

Supplies are needed to fuel the war effort against the sinister forces of Ahn’Qiraj. You’ll need to work alongside other members of your faction to contribute the resources needed open the ancient citadel’s gates and begin your siege on the Ruins of Ahn’Qiraj and the Temple of Ahn’Qiraj.

Both Horde and the Alliance will need to bring a steady stream of supplies to the Valley of Spirits in Orgrimmar or to the Military Ward in Ironforge. Each turn-in will reward Ahn’Qiraj
