Hmm...
You want me to explain Gallery inter-dimensional travels and universes, huh?
Well, let's do this.
The legend of the "Valhalla" dimension- a story of war. Part 1.
Before all else, there was our reality.
In it were birthed the Creators, men and women of incredible power and imagination.
All that has come and will come is because of them.
Now, the creators were usually quite peaceful.
But as with all positions of power, comes great corruption.
Survivor was once the peaceful creator of the Dawn of Death universe, in which he poured all of his creativity and story telling. Engineering it to be as dark but also light as possible for its genre.
However, with time, his thirst for power grew. He had a falling out with the older creators, as he deemed them blind, and they deemed him arrogant.
Zarry, the most joker of them all, decided that he would mock Survivor ironically, yet it backfired greatly.
From this harmless joke came a creature, an abomination, that would come to be named the Critisizer, destroyer of worlds, roaster of posts, and killer of comics.
At first, Survivor, in all of his arrogance, thought he could control this thing.
Oh how wrong he was.
Over time it gathered in strength and grew, untill it consumed him entirely.
And this started the war on the elders, one that would go down in history as an odyssey of great danger, death, and destruction.
The Critisizer was eventually stopped through the combined forces of Nato, Sabree, Green, Jason, Charlie, and Joe, the council of the ancients, who were aided by Nigel, Diesel, Zarry, Arbiter25 and Rogue, younger but still quite original members.
In that fight perished many more though, Tis, Arbiterofblocks, CMK, etc. And they were to be remembered as heroes whose sacrifice would never be forgotten.
Yet, the Critisizer was not destroyed.
Through a sacred ritual they were able to exhort him from Survivor, and trap him within a cell, that was to be guarded for all of infinity.
