Liam and his grandparents arrived in America, they decided to part ways. Liam had already talked to them about going into the world on his own. Liam firstly took admission at Harvard who was after seeing his record and his being a member of the royal family was more than happy to give. In America, Liam owned 3 castles 28 houses and about 39 properties so Liam wasn't particularly worried about living anyway and he also is one of the richest in both Wizarding and Muggle world wasn't worried.
Liam took it slow while completing management and a legal degree from Harvard in one year sought to continue studies at MIT talking various engineering and Master of Science degrees within three years, with the help of Hope and little bit magic, Liam prevented anyone from leaking anything thus didn't bring any light onto himself. He like the SAO world started with a small company that dealt exclusively in energy such as petroleum and such while using Hope to form many branch companies into all fields. Knowing Rons feeling for Hermione and Hermione's internal struggle of loving Ron, Liam didn't have many expectations from her but Hermione proved him wrong, Ron, after tasting some victory in his sixth year and knowing Hermione feeling for Liam, didn't pursue her, Hermione too with her promise didn't saw in that light thus remained friends only, the three years went as the plot which Dumbledore first being removed from his post after the "Dumbledore's Army" exposer then Black dying and people truly seeing Voldemort and finally being Harry and Dumbledor followed by Dumbledor and harry discovering about Horcruxes from Slughorn and then finally the Dumbledore and Harry going in search of the Horcruxes. Liam knowing the story knew the time of Dumbledore has come. And the chance of taking ownership over the elder wand will come soon.
In the past 2 and a half years, Liam has not wasted his time in the muggle world only he knew almost everything regarding all the subjects and his company was managed by Hope, Liam not wasting any time of these 3 years used his companies influence along with a little bit of magic put all the cities, townes under surveillance, using muggles who put up cameras for him everywhere, he then found an interesting men a man who turned a bit mental from a torture done to him by a witch, all Liam did was whispered an Idea into his ear of the man and left him alone for now. The name of the man was Harold Finch who worked with his friend in their own company IFT with Harold being the brain and Nathan Ingram his classmate from MIT being the face.
Liam after watching the death of Dumbeldore decided to go and get that ownership out of Draco Malfoy's hand.
Liam dressed in complete black and put on the mask the same as Tobi, Apparition to Malfoy manor. He activated his Byakugan making sure Draco is their went in the House, simply bounded everyone with the manor with chains including Draco and his mother.
Liam calmly with both his Byakugan active making his eyes completely white with veins coming out of them walked into the manor not wanting to waste any time. Liam directly went to Draco and said: I will give you one opportunity if you could defeat me I will leave if not, I will kill your mother.
Draco filled with fear for his and his mother's life took the dueling stand. Liam not giving any opportunity and not wanting to waste time disarmed him. After which he simply disappeared and appeared in front of the newly constructed Dumbledor tomb. Using his dementor form went inside and took the wand out of the old dead men's hand. Thus finally collecting the 2nd deadly Hollow, after doing so Liam disappeared again and went back to America. Leaving no traces of him ever being there with the help of Hope.
With only a few months left before the battle of Hogwarts, Liam finally got the answer between Ron and Harmonie when Ron angry with Harry left the trio after which Ron destroying the Horcruxes with the Gryffindor's sword showing an image of Liam and Harmonie kissing and later Ron confessing to both that the real reason he was angry was due to him in love with Harmonie and hating Liam for having her. Harry saw this as stuck between a rock and a hard place as one party is his best friend while another is his savior who decided to not take part in between them. Meanwhile with a conflicted mind of Ron's confession of liking her, Harmonie also slowly realizes her feelings for Ron and her loneliness due to Liam not being there for her in a moment of hesitation kissed Ron but later refused Ron stating that she was confused for a moment with Ron stating that if she likes him then she should be with him to which Harmonie stating to talk about after the war is over. Liam smiled seeing this and taking a deep sign decided to visit his grandparents telling them about Harmonie and his situation with her while leaving the part of him being a creep who placed nanotech with which he can spy on her 24/7. His grandparents told him that he should simply let her have her choice not to force anything as forced love is worse than not being loved sometimes. Listening to his grandparents, Liam left the thought alone. He informed his grandparents about the upcoming battle and his plan to take part in it and requested them to stay here. Knowing their grandson's power and maturity, his grandparents wished him and promised to not interfere.
With this promise and heartbroken, Liam decided to start his plan for the originals, at first he was planning on letting Hope Michaelson being born but later decided that Killing them as early as he can and leave this world as soon as he can. He would just simply go into any random world after this one.
Liam with the arrival of the trio at the Hogsmeade made his way toward Hogwarts, Slowly making his way toward the rooms of requirement where he knew the students were hiding in his invisible form. He observed as the plot happened of Luna showing Harry the path to find Ravenclaw's crown and Liam didn't go after them but watched Ron and Harmonie interact with each other, he realized that the true thing he was hurt about was that he missed Asuna nothing else. Sighting at his insight, Liam saw Snape order Students to gather within the Great Hall.
Liam decided it was time to join in on the fun. He saw the member of the order of Phoenix gathering outside the Great Hall, He appeared in front of the Gate surprising everyone in the order, some even draw out their wands.
Liam facing the gate put his hand on it said in a low cold voice: Are you ready to dance?
The Huge gate of Great Hall blew up in pieces.
Harry who was about to walk in the front along with everyone all the professors and students were stunted. Liam wearing a Black suit calmly walked in and looked at snape and calmly said: I said: "Are you ready to dance?"
