Harry could see the medley of emotions upon his Dragon's face and found much pleasure in it, he loved to tease his future lovers having the options, wasn't usual for him being at the mercy of another's sexual whims and fancies. The advantage of living so long is the fact he could no longer remember the man's face but still felt once in awhile the things done to him, punishments for resisting complete and utter torture; which was why he was so eager to receive Tom's gift the hunger for blood not of innocents; never innocents only wicked bastards of the worst kind; but eventually even that blurred over the lines.
Happily became a monster for him to stay with him, in his burning intense love to never go back to the cold, till they got separated he had gone blood crazy ended up at a Druid Monastery, they restrained him with magic not used to such a creature such as he they kept him for a good long decade trying to cure him of his condition which ofcourse failed till Dean found him. Dean informed them of who he was he helped them bring him back to himself accepting non-human blood alternatives, when finally no longer violent taught him their ways.
He and Dean made their home there for another couple centuries he still missed Tom terribly, often saw his rages in his dreams from his absence but also glad to be away from the influence he had over him. Dean was especially glad to finally have his friend back stained yes, but not lost they even built their own ship to kill time.
The Druid brothers very much enjoyed that and participated; after completion took trips to other Druid isles to introduce their newest uninitiated immortal brothers; many were wary of them for good reason but after some meetings they were taking in under tutelage of the Head Druid Griopori learned much and all from the man and with their ship gave them the job of procuring healing herbs from all areas of the world a very awesome time for all parties even helping with recruitment pilgrimage for all Religions even was able to reconnect Dean with his lost family in spite of his condition they accepted them both stayed close to their Druid brothers.
Unfortunately talk began of them reaching the one person they didn't want to hear, coming back to their Home Isle all was dead, tortured and drained even the children; brought him to blinding rage and exacted revenge upon Tom and his followers. Their other Brothers wanted to join them but the Heads wouldn't allow it and put both Harry and Dean in a deep sleep and in hiding till the Heat die down they were awaken in the early 1600's with the release they were given their ship back and sent on their way.
They didn't know what to do with themselves but knew they had to stay under Tom's Radar and not get close to others for fear of their deaths, spent most time in solitude traveling the waves digging into the smuggling game for sustenance building a sort of empire as well practicing their craft mostly cloaking and Warding along with offense and defense of all kinds of manner.
They came out in public rarely but never for too long and now with the new lease of life and child he wasn't gonna take more chances; but was very interested in this blonde and his fiery personality, that matched his own.
The kids swarmed in on him being such a famous rock star, it was funny to watch the kids practically go into conniption from starstruckery at the sight of The Dragon as was Draco's stage name.
"Kids, kids!" Harry was able to get their attention. "I'm leaving today and already you've forgotten me."
The students looked so torn between them that Harry burst out laughing, with a disapproving glare McGonagall picked up one of the erasers and smartly launched it at his head.
"Mr. Potter if you're quite done being a child we have things to do before the Farewell Concert tonight."
Harry moved the Guitar to his side, leaned against his desk. "Ah yes Graduation, who here can't wait for that?"
The kids again began another round of enthusiasm making McGonagall give out a shrill whistle to quiet them down again.
"Back to your seats." She snapped. "I will not have you unruly galoots embarrassing this institution with your rough housing revelry."
They all returned to their seats with abject fear of her wrath.
"Shows what she knows about rough housing." Harry added, the class laughs as he ducked another eraser.
McGonagall moved to the center of the room; Malfoy followed eyes still on Potter who was fucking smirking in amusement, he'd show him humor once he got his hands on him.
"Okay children While Malfoy senior is out his son will graciously take his place till he is better now I will leave with him to get acquainted. Mr. Potter with me please.
As McGonagall left Harry slung his arm around Draco's shoulders facing the class.
"Now kids Junior here is as scary as the other Malfoy." Harry slaps his ass, making Draco jump with an eep! "All yours Blondie."
The kids giggled as Harry quickly vacated the room as Draco glared in retribution till that glare was turned on them many gulped as a wicked smirk donned his face.
"Mr. Potter is right I'm not like my father, I'm so much worse."
