Once a powerful and brutish grem that worked for Exodus to hunt down and maim problematic grems and escaped cyphers. Their existence was kept very hushed and under the table, even among the scientists of the company. He was skillful and did his job well, and as long as he successfully completed his tasks, the company was happy. Though things could often get dirty, the grem never complained about their work. They closed off their mind and emotions to what they were having to do to their once fellow grem-kind, and in return they got cold, hard-earned cash to keep their trap shut and to complete the tasks as requested. They used whatever weapons necessary to apprehend, and often times terminate wanted targets. Life was going good for them.

Until an accident happened. They were a bit too careless when dealing with an escaped cypherus that once worked for the corporation. The cypher got into ther head, delved into their deepest emotions that they tried so hard to turn off and keep on lock down during work, and in response they let information slip that shouldn't have been known to anyone. The cypherus managed to escape with their life and the precious intelligence that the grem had let slip about the corporation and their plans. Exodus was furious with him. Furious that he let one of their precious projects get away.

But the grem didn't find this out until it was too late. Having no family, no relatives, and no friends, made it all the easier for the corporation to dispose of the rogue grem. The price of his failure was his head. Exodus sent out their next best employees to apprehend and terminate Grimsley, hoping to cut off any lose ties that could come from their mistakes. Grimsley was attacked and left for dead, his files erased from the Exodus database. They thought that was the end of it...but they were wrong.

He was not dead - far from it - and now he is nothing but angry. The incident caused dormant powers to awaken within him, and Grimsley went into hiding and began to prepare for the downfall of Exodus. Now, he hides in the shadows, working as a deadly, calculating assassin. He's so proficient with his job he's become known as the Grem Reaper. He's waiting for the day to bring Exodus down, and anyone who works for them along with it.
