In the second weekly Archives quest, Archives: Seeking History, players learn more about why the Titan Pantheon brought order to Azeroth, and the facilities they built to do so. WARNING: Spoilers for The War Within! The Message of the Archive Archaedas says: On Azeroth, the Pantheon sensed a powerful source of corruption.
To protect the Worldsoul, they sent us, the keepers, to lead the titanforged forces into battle. Archaedas says: In time, we rooted out and defeated the threat, imprisoning its last vestiges in the deep places of the world.
Archaedas says: Then, led by Aman'Thul himself, the titans set toward studying the soul of Azeroth to determine whether it truly was the one they sought.
Archaedas says: To aid the titans, we keepers were tasked with engineering the Manifold--a vast, world-spanning complex of machines, forges and installations.
Archaedas says: Working in tandem, they would bring order to Azeroth, and create a means by which the Pantheon could examine the Worldsoul in depth.
