The Wizarding World has been kept a secret from Harry for eleven years. Some secrets are better left unexplored - they have a nasty tendency to kill those who look too closely. After all, to be a wizard is to walk with death - though Harry will press on into the mysteries of magic. Anything is better than Privet Drive. AU, Type Moon crossover. Not a romance.
A side story to Fate: Revelation Online, by daniel gudman. Faced with the reality of a Death Game, what would you do? Would you flee the thought of death like a coward? It is a doomed effort, for even cowards cannot escape the truth: to be a magus is to walk with death. Avoiding all the monsters in the game simply leaves one with more time to walk that razor's edge.
