The Endless War

I have lived my entire life not believing in God, or the supernatural, and as it turns out, I was horribly wrong.
Not only do Heaven and Hell actually exist, they are at war.
When I gave my life to protect my friends and comrades, God saw fit to present me with unfathomable power.
Now I must learn how to harness this new power, and use it in the fight against Lucifer and his endless hordes, but also to protect those I care about.
