"Stalin himself cannot stare Nikolai in the eye, no one can. There, in his eyes, you will see the soul of a man burning with the hatred of all things living. His closet is full of skeletons, many of them with the flesh still attached.
Early in his career, Nikolai had quickly made his way up through the party ranks by killing the next man in line, and by marrying politically. Ultimately, his aspirations all came crashing down after his fifth wife mysteriously died while cleaning his axe with her neck. Little did he know that she had been sleeping with a high ranking party official on the side. This made Nikolai infamous, and his reputation spread quickly through the party. It was not long before Stalin himself had heard about Nikolai. More importantly, he feared Nikolai. As soon as the war started, our hero was dropped on the front lines and forgotten about, where he wallowed in self pity and Vodka for several years.
There are many weapons in his arsenal, not least of which is his breath.
