It was witnessed by all. The great war between mages and an externalist.
The few snippets of the war that were recorded by some brave players who dared to get close were spread throughout the internet. Making one wonder, where was the limit?
The shockwave alone was enough to kill multiple grade 3 players and those that did survive suffered from grievous injuries, which forced them to kill themselves in turn.
But there were those that stayed in the planar world till the end, those that remained at a distance and witnessed the arrival of the giant dragon and the void rupturing breath it exhaled on to this weak plane.
Annihilating it from existence at the end.
Followed up by the end of the world, with a drifting and raging beautiful machine which raged towards the void, but no sound ever reached the players. For they were dying as well, eaten away by the void, turning into dark matters, forever assimilating into the void.
