Infinite Expanse

Traveling to a different dimension should have been in the job description. But well... It's too late now.

The world did not blink when the man named Zachery Elmore disappeared. Even as a world class mathematician his disappearance had little impact. Where would someone like him go? Do mathematicians even do vacation? Would it be the coast? An isolated cabin? But that question was soon answered when they found him comatose, head connected to an amalgamation of computers. He was alive, but his mind was gone. And where it had gone, no one knew.

And that's where a certain organization came in. Tasked with finding the man named Zachery Elmore, our protagonist must now travel to this "other world", and hopefully not die in the process.
