The Omniscient Conscript

In a universe similar to our own, the world is engulfed in another World War. The tensions in Europa had been satiated for twenty years, but now those same countries were at each other's throats again. Midst the chaos is born a child, Magnus Charles Licinius, who gets conscripted at the age of 22 to go fight in Europa as part of the United Provinces of Columbia's war effort. During his first battle, he is shot and crushed by a plane, and ends up in a weird city. After being "exterminated" in that weird dream, he wakes up again, unharmed. What will happen to Magnus as he travels across Europa in effort to end the war?
