It didn't take long for Harry to settle in. Aunty B, Hermione and Draco made sure of it. He also learnt some techniques from some of the others.
From Hermione he learnt the art of truth-telling, one that she herself learnt after the attacks on Nemphany. Now Harry could tell the trustworthy from the untrustworthy.
From Aunty B he learnt how to shape shift. The difference between shape shifting and being an animagus was simple. Shapeshifters could turn into whatever animal they wanted but animagi could only turn into an animal that fit their personality best. Also shape shifters had to be careful; they would have all the instincts of the animal they changed into whereas animagi could keep their thoughts and instincts.
From the vampire of Nemphany, Rio, he learnt how to seduce both men and women to do his bidding, however it did not work on vampires, elves or nymphs. Rio also taught Harry how to change into his vampire form which wasn't much different to his normal form except he had a dark bluish tint to his hair and pointy fangs and his body became more well defined in which Draco was more then willing to explore.
Speaking of Draco, he taught Harry, after mind communication and thought reading, the ways to place a mind block on himself which was much more affective then Occulemcy because no amount of torture could bring it down, it did not protect him however from the Imperius curse or other controlling curses/potions. He also taught him how to survive being raped as well as wandless healing charms to heal himself and potions he could easily make. In case he was ever bonded up by shackles or anything else.
Draco also taught him how to protect the Elvin part of his heart.
But nothing could have prepared him for Draco's disappearance.
It had happened when Draco had returned to Malfoy Manor to greet Narcissa as she returned from a magical spa in Hawaii. One way or another Voldermort had found out about Draco being a part of the Emeralds and placed him under a potion similar to the Imperius. But it was ten times more difficult to break through and if anyone attempts to bring you out of it both the victim and the attempted rescuer will be killed instantly.
Two weeks later Harry suffered a nervous breakdown.
One week later his memory of the Emeralds and everything he had learned was gone and he was yet again at the Dursleys as if nothing had happened. All of his lost memories were replaced.
And so it remained that way for an entire year, after Professor Dumbledore's death and before the 'golden trio' as they were known set out for their mission.
