He hasn't had the best life, in fact, some would argue that his life couldn't have been worse, but there's still hope, even for a nihilist. As when an expedition to colonize the moon quickly turns into a disaster, he is swallowed whole by an anomaly and spat out somewhere completely different.
Here one can conjure flames with words and summon thunderclouds with a shout, but it's not all fantasia and ecstasy. The world seemed peaceful enough, but as he learns more and more. He realizes everything he sees is a facade, and what's truly underneath is a civilization built on blood and war. In fact, the whole world is in a state of war.
