Moved by the Law of Probability by fringeperson reviews
The probability of Harry Potter living a completely normal life was low, but that was okay. Normality is over-rated and boring anyway. He's managed to do some pretty interesting things with his life since the war. Don't own, not canon compliant.

Life Sucks and then you die by Iorek Byrnison reviews
As it was, even if wizards were generally more accepting of the unexplainable, no wizard would accept a 600ish year old Harry Potter without the inclusion of the Philosopher's stone, so he faded into the background, concealing his appearance. Until the day a robot crashed through the ceiling of Potter manor. The magically enforced stone ceiling. Ouch. AU fic, Beware of wormholes.
