In the first years of the Revalationary Era, a new wave of raids was launched by the Githyanki on several Prime Worlds. These attacks might have been of little significance to the rest of the cosmos if not for one detail-they were all colonies of Ortho. The planet that gave birth to the Harmonium mobilized its forces to bring the fight for peace to the Astral Plane.
The Astral War would last over two centuries. The forces of Ortho found common cause with the monastic Astral Norse and the enigmatic Fraal, while the Githyanki were aided by the Doomguard. In their efforts to gain a decisive edge, both sides harnessed the technological revolution taking place in a few corners of the Prime Material. In doing so, industrialization spread rapidly throughout the Multiverse. Despite the limited scope of the Astral War (in comparison to the apocalyptic Pantheon War or the unending Blood War), it nevertheless brought great change to the cosmos.
So the astral war was a techno revolution for the multiverse speeding up the spread of technology and creating the need for it?
