Liam went into full emotional support mode with Bonnie for Elena while waiting for the next semester to begin in which Stephan will join in.
Soon Stephan enrolled in school after which Damon too came into town, and the story began.
Liam patiently watched all the drama happen and how about Elena becoming close with Stephan then learning she is adopted and stuff which soon ended with Katherine Pierce coming into town acting like a big shot and killing John Gilbert.
Soon like the plot, Klaus got news regarding the moonstone and the doppelganger also come into town, followed by Elijah and then the witches.
Liam has already taken the Vampir hunter and inserted various black matter weapon's into him when he moved into the town. He let Michael suffer alone hungry making him feel like he is in hell.
He saw as Greta along with other witches came into town bringing the body of real Klaus. He waited for the spell to be performed and bonnie coming in all her power while trying to kill Klaus when Elijah came and ripped through Klaus's ribs grabbing his heart. Seeing that the time is now, Liam who was watching everything while standing there invisible came into being surprising bonnie who was standing at a distance.
Liam looked as Klaus told Elijah that his siblings are not at the bottom of the ocean but with him, and Elijah picking Klaus to run away, seeing this Liam raised his hand.
Bonnie who was watching for the distance and screaming at Liam to run away, saw this and got surprised as she saw both Elijah and Klaus hanging in the air unable to move, Liam waved another hand of his throwing Damon and the rest who rushed to Elena away. Liam grazed Elena's cheek a little then looked at Bonnie who was standing their stunt informing her Elena is going to be okay.
Klaus and Elijah both hang in the air struggling to move. Liam went in front of them and bowed.
Liam: Allow me to introduce myself, I'm Liam Mikaelson, the last alive Mikaelson. You don't need to worry I already have the rest of your siblings.
Liam took out a dagger made out of black matter and embedded into Elijah making him dragging him into sleep like the rest of the sibling while he also touched Klaus and embedded nanotech into him. Let him go. Klaus saw this as a moment of freedom decided to focus on his transformation first and then let come for his brother.
Liam in the meantime with the help of nanotech changed into his own 21 self, He looked at Bonnie who was holding Elena and said He is known as the boogeyman in witch culture if she even wants to find him and then disappeared.
Liam has already ordered his men to move the bodies of all the Mikaelson's when Klaus come into town, He took the body of Elijah and placed him into a similar coffin. He took out the black mass dragger out of Elijah's body walking him up, he remembered Elijah had the most pages of Esther's grimoires. He showed Elijah the body of all his siblings hiding his parents, He threatened Elijah that he will deliver all the bodies to Mikael if Elijah didn't bring all Esther's grimoires pages to him.
The biggest problem with the originals and their families was that they were unable to stay dead, always coming back alive and trying to kill each other. Using the idea of Voldemort, Liam first chose 7 draggers and made them into Horcrux of the 5 people he had with him Finn, Kol, Rebekah, Mikael, and finally Esther. After making sure that their soul is trapped without any possibility of leaving Liam activated his white oak tree genus burning the bodies of all the originals present except Klaus who was ramping around in his Wolf form, After burning all of their bodies Liam created Fiendfyre destroying all the Horcrux and their soul within them leaving no chance for revival. Liam using black mass dissolved all the leftover material such as ashes and broken pieces of the draggers. Just to make sure noting collected to them isn't leftover
After 3 days, Klaus woke up after completing his transformation to a wolf, he remembered seeing a boy who introduced himself as the last Mikaelson and that he had taken Elijah while saying he has rest of the siblings. Klaus with caution fled after getting clothes he wasn't worried about what will happen to his siblings believing that they are immortals, he was worried that the boy will release them all which will make things for him to against all the siblings together at once. He rushed to the storage house where he has hidden the coffins, Liam watched everything from the nanotech he has left on Klaus, he seats there in the storage patiently. Soon Klaus came rushing in and looked at all the coffins missing and that boy sitting on what looked like a throne-like stone seat.
Klaus seeing the boy directly went for the kill, but he couldn't move at all, Liam smiled and said: I will give you too choices one bring me all your mother's grimoires which you and your siblings collected throughout the years or second I will wake up one of your siblings and torture them along with you of course or better I will send a message to Mikael about your siblings and their sleep so he will just have to walk here and stab your siblings then He and I can come for you. Your choice.
Liam then waved his hand breaking Klaus's head. He told one of his men to go and send Klaus back to mystic falls.
Liam waited for about 2 months as he watched Liam first run and try to hide but Liam always after 3 days send him pictures of some Coffin along with the fake picture of Mikael making him understand he can't run or hide. Klaus then knowing he has to do Liam's bidding, for now, started gathering all the pages from his mother's Grimoires he soon met with Elijah who also was searching for the mother's grimoires, both formulated a plan to attack Liam after recovering the bodies of their siblings from Liam.
Liam patiently waited for 3 months after which he saw Klaus and Elijah returning to mystic falls separately to make him believe they are not working together, Elijah came first with the pages he had and gave them to Liam. Liam took them and smiled telling him to wait as he will inform his people to bring all the bodies here. Liam took out his phone while pretending to be calling someone, cast a silence spell to make it seem real.
Soon Klaus too came in with the pages, Liam taking them informed the siblings are already on their way. Klaus watched Elijah who singled to attack. Klaus rushed and ripped the heart of Liam out of his body. Liam pretended to be dead and fell to the ground. Klaus picked Liam's phone but as he bow down to take the phone out of Liam's pocket which was lying on the ground felt his inside on fire. Liam calmly out up from the ground and put a black matter dragger onto Elijah while placing another dragger into Klaus which he found to be a modified golden-white oak ash one which Kol was working on but was unable to complete. Liam taking some blood out of Klaus started the process of trapping their soul and turning them into Horcrux while burning the bodies off both Mikaelson's and then absorbed their ash. He then felt the vampires around America turn to ash as their Sireline head is dead. Using Fiendfyre he destroyed both the Horcrux again. Thus ending and destroying the originals only leaving Freya from the family who as per his task he didn't have to kill.
Liam took all the pages of Esther's grimoires after reading them consumed them with his black matter thus ending any possibility of anyone using them ever. Making it impossible for a kind of resurrection Spell to be constructed by Davina or any other witch.
Soon the space in front tore and a voice came out
??? - The task is fulfilled what do you want?
Liam - Lord would it be possible for me to take the black matter in my body to the next world with myself?
??? - The matter used in making the black mass is from this world so I can permit you to take the material, you will have to use your other wish to take the black mass with you.
Liam - Thank you Lord for providing me with guidance.
Liam felt that the ticket to the next world appear in his pocket taking it out Liam nodded.
Liam decided to visit his grandparents and ask them to join him via world seed, they can stay alive with the world seed without any worry.
His grandparents were reluctant to leave all their friends and such so all Liam could do was use his nanotech on them making them Immortal like him by changing their DNA structure to that of a phoenix. Liam also made a mega Hope station in his grandparent's home while also giving them various Castle and such where they can retire and remain secure. He also used his witches and Wizards to spread the end of the original family and the vampire species as in whole crediting it to the Boogeyman which was his persona throughout the world. He made a system in which those 35+ witches will serve as the branch of the Albert family and maintain the balance between muggles and the magical world.
He established the 40 or so Humans to establish their line while serving as chains for his family within the muggle world.
He also went to each house and castle he owned and used his magic to make them as secure as possible if his grandparents even use them.
He also started compiling books on every subject within the system but stopped when Hope informed him that his parents in the Sword art online world were near death.
Liam informed his grandparents of his departure and telling them he is always connected to them though Hope via which they can always connect to him.
Liam took out his ticket and the space in front of him tore sucking him in. Liam found himself standing in front of the young men again who greeted him in the same manner: Greeting son I have informed the manager of your arrival. Welcome to Hotel del Luna.
Liam turned and saw the young women coming toward him: Fellow me you know the process.
Liam: I was hoping to return to my first world my parents in that world are dying.
Young women: Hm... okay come, let's go.
Liam and young women went into the same room, Liam looked at both are bodies which looked very handsome.
Young women: the Same process sleep and tell them about wanting to go back to the first or whatever world you want to go to.
Liam laid on the bed but before he could wish or anything his soul flew out of his body and went into Lu An's body.
Liam/Lu An stood up in his previous body and looked at the women.
Young women: Okay now you can go out of the hotel and fulfill whichever task you wanted to do in this world, after doing it come back to the Hotel.
Liam/Lu An stood up and went away.
