Pheonix's and dragons; Pheonix Diggory x Bill Weasley

(Golden trio era) When Pheonix finally gets to her breaking point at Hogwarts she drops out at the end of her fifth year and runs away, after a long night of running she finds a peculiar place with peculiar people in it, 'The Sanctuary' they call it, she stays there for three year, until she's eighteen, by then she's risen in the ranks and secretly practiced her magic even though it's banned. She's actually really really good, better than most witches and even more so than most wizards.

Bill Weasley meets her and is instantly curious about her but she's fifteen at the time so he's not that interested in her, then three years later she shows up with a tattooed arm and bloody injuries all over her from an apparent 'war' he helps his mum heal her but she still doesn't trust anyone, yet she's so ravishingly stunning and the way she treats his younger siblings melts his heart away

Can she find the courage to push through and forget about her traumatic past? Bill does hope so as he's waiting on her to finally trust him and his family, then what with the whole wizarding war coming up she has to use her capabilities to protect her new found friends

Along the way she saves a Basilisk from Harry and turns the giant snake back into its true form, a dragon. This dragons name is Leto and can curiously speak to Phoenix

Then of course the Sanctuary is falling to bits, war is raging at her once called home and she's been promoted as a warrior for the rebellion. She soon finds the place has been overrun with death eaters and has to leave with the few people who are neither death eater or too scared to, when war rages Voldemort will do anything to win

Kill the girl who stole his basilisk?

Of course he would.
