The Knight of Hades

In the kingdom of Hellion, there lies a renowned adventurers' guild of the name of : The Red Army. It is the origin place of many great heroes of the kingdom, and in some cases: the world. The most notable of which are: Calista Fawkes the Holy Knight, Bendoverski Jerckov the Great (perverted) Wizard, Pyotr Harkov the Marksman (archer), and many more.

All of them came from several races as well, such as elves, humans (obviously), and the rare, dark elves. However, the guild has increased in fame when a mysterious black armoured man joined its ranks. His name is Ivan Kuznetsov. At first he seems to appear as an ordinary knight, however, as time goes on, suspicions arise. Who is he, and why is he here?
