When Harry was 1 years old, is when the Dark Lord came to their home to kill the prophecy child

He failed

The Dark Lord killed James Pott-er, meanwhile Lily Pott-er took her baby and disapparated

The Dark Lord raged, yes, however the war was won, the Dark Lords reign begun once and for all eternity

However, somewhere in a hidden house warded to hell and back Lily Pott-er raised Harry, her son. Not under those names of course, no, they were now Elliana Evans and Conner Evans

Harry was taught to duel, how to defend, every type of magic, Light and Dark, but his mother as soon as he could hold a wand

Then the letter came on 'Conner Evans' 11th birthday

They go shopping for a wand, a proper one, for Harry. Holly and Pheonix Feather, 11 inches. A brother wand of the Dark Lords. He must not find out. It would draw too much attention

Elliana and her son go to the plaform, and Elliana Evans wakes Connor goodbye as he gets on the train to Hogwards.

'Conner Evans' knows to keep his head down. not draw attention. Survive and thats it

He finds an empty compartment and sits down, opening a book and reading quietly
