Once and Future King
When Albus Dumbledore hears of a Chosen One with power the Dark Lord knows not, he thinks maybe he doesn't want this boy prophesied to defeat Lord Voldemort to grow up in the Wizarding world. He thinks Harry Potter should grow up loved by his family, and Voldemort be destroyed so there is no need for Harry to ever realize his power.
When you dabble with improvised ritual magic, you should be aware there might be unforeseen consequences.
For example: souls touch.
Harry continues to struggle with adapting to and understanding the wizarding world, which increasingly seems to have backed itself into a corner by allowing rampant anti-Muggle belief to coexist with rampant ignorance of the Muggle world. Of course, there is also the problem of being a "Light" icon in Slytherin, not to mention the fact that someone seems determined to hamstring Harry's independence.
