Griffin and Snake

Hadrian James Potter just can't catch a break can he? After suffering a year of utter Hell at Hogwarts the so-called 'Safest School' in the world. The teen has actually been left alone by the people he's supposed to call 'Family', with that said the night of his 15th birthday he goes through a surprise inheritance and has a very enlightening talk with Death.
What happens when Albus Dumbledore's precious 'Weapon' goes back in time as who 'She' is really meant to be?
Wait...hold up! Yes, you read that correctly 'SHE' What the fuck did Albus too-many-titles Dumbledore do?
Also what happens when she ends up in the same era as the Marauders? She falls in love with her Werewolf Mate...DUH!
