A young Harry Potter, abandoned on the streets, is taken in by a man with a mysterious motive. When his new muggle tattoo suddenly animates, he is soon learning forbidden magic and planning to infiltrate the wizarding world on behalf of the "ordinary" people. But nothing is ever that black and white. (Runes, Blood Magic, Parseltongue, Slytherin!Harry) (SEE NOTE 1st Chapter)
