Harry Potter and the Really Old Sorcerer's Shiny Red Rock

Re-write of all books where: Severus is Harry's father. Dumbledore and Ron are not loved characters. Harry and Hermione are sorted differently. Draco is a friend. Eventual yaoi. Fred and Hedwig don't die. It will take me long to finish, but it will make sense within the context of Rowling's original story and I won't drop the story. More details in huge A.N. in first chapter.
