Hidden From My Mate

Harry Potter is only a ten years old when he finds out he can talk to snakes and reta his new snake tell him about the wizording world and he gets confidince to take down the durselys and he goes to digone alley and meets Draco and they become best friends but what happens when he finds out on his 13th birthday he's a malfoy to as well as a roaly vampire/dark elf but who's his mate and why did dumbledore hide his true identity from him

(there are some ideas that aren't fully mine but in this there will be dombledore, hermione, and weasley bashing expect George and Fred are safe because I love them)
