Somehow or another, your life has ended. You find yourself in a boat, having just beached itself on an island. When you open your eyes, there is no one there. No note. Nothing, except, strangely enough, a PDA with your name inscribed on it in your native language. Below it are runic symbols that when translated would say 'Valhalla'.
Valhalla. The Elysian Fields. Purgatory. By any name, the same place. A home to warriors and champions, and those who passed before their time but for the good of another. This is where you find yourself. A path through the trees will take you to a fairly modern city, where you have the choice to live free from the burdens of your previous life.
By the way, don't mind the Greek gods. They enjoy their games, and will be more than happy to put you in your place when necessary.
