In a universe located at the edge of the Material Substrate, lay a very peculiar white planet. WAN. This planet, as large as the usual solar systems, abridged an advanced civilization. A humanoid-like species who used technology to fight anyone or anything that disrupted the balance of the Material Substrate. They were the Wanderers.
Their domain currently spans several universes throughout the Substrate, but they have yet to achieve all-encompassing influence. It is one of their goals. Their other goals include fighting against the equational machines and anomalous phenomena that should not exist. In a sense, they can be considered the protectors of the multiverse, but only when it comes to large-scale things.
Recently, they got a hold of an individual that was supposedly spreading terror and murder across the cosmos. So powerful was he, he had decimated all living organisms of at least three million universes in a span of days. His name was Antrax, an extremely powerful immortal creature that defied comprehension.
It was the first time they have seen such species. The only other one that could compare was the Hex. The Wanderers wondered if the two were related. And upon digging into several layers of information and evidence, they were right. However, both species were enemies of one another. Good, it was less work, they thought. To fight against both would be way too troublesome.
Thus, they focused on how to deal with the God of War, the title that was so spread across the cosmos.
One day, Antrax walked into the edges of the Substrate. The Wanderers saw this as an opportunity to challenge him directly, seeing as he was quite close to them.
Measure his strength, and from there, decide the best course of action.
