Graymark

Have you ever been so angry that you wanted to break the laws of physics and throw down with a cosmic being? Well, you might if you’re Great—no, not “great”; I mean Great the Executioner. On planet Graymark, where the law decrees that all sinners must die, Great makes a name for himself butchering criminals in their thousands. Except now the law is no more, and Great must stand trial before the King of the Cosmos, Lohumlagaha. Enraged by fate, Great takes up his sword. It's just one last time… Or is it?
