This is a nice place to start...

"An abandoned library?... I might start here..."
Marik was walking in Rose garden, he knew there was a lot to knew about himself, he knew that something was missing. The slayer was using his mask, he moved his hand with a knife and placed it in the mask's mouth "Sometimes things can be interesting" the masked man walked a lot, during a big while ignoring anyone who tried to talk to him, he went to a abandoned place and went out from a different door than the one he entered from, he went to stores looking for old stuff, but at the end he finished standing in front of an abandoned library thinking.

"An abandoned library?... I might start to find something here..." Marik gave a step and tried to open the door but it was locked, he placed his hand in the door and it started to freeze, when it was full of ice the masked mage kicked it breaking the door. He gave some steps, it was a very small library, it had 20 or 30 books, but not more. There was a table, with some books over it and two chairs around the table.
Marik went closer to the table and found some interesting books about a magic called "Supēsu hakai", the slayer laughed and took them placing them under his cloth "Whats this...?" under the books he took, another book was laying broken and full of dust, he took it and blew off the dust with his hand "My life" by "W. Anderson" Marik laughed and opened the book "So Anderson..." he started to read, but the book was big, he preferred to sit a while and finish it.

"So... Hanna... Was just another girl..." Marik laughed, he laughed loud, very loud "I fell in love with a girl that I didn't even know, I can't believe it" the slayer kept laughing during some seconds, when he finally stopped he kept reading "Three of os... So its not only me?..." Marik kept reading, and then closed the book as hard as he could "They know we are going to meet, thats our destiny, Marik, Lex and Luxin... The three brothers... Maybe they will help me... Maybe they will give justice to this world with me..." Marik placed the book in the table and then walked around the place looking for more information. He smelled something, he heard something, someone was entering... The second brother.

Lex was walking through Rose garden with a bit of a stern look on his face. Something seemed to draw him through town. The people walked passed him and didn't take any notice to him or to anyone else they walked passed. They minded their own business and went about their daily lives day by day, not noticing anything that happened around them or anyone they walked past. "Dammit..." Lex muttered to himself "I am bigger than this... These people should fear me!" he growled as he got a weird look from someone who he snapped his head towards with a mean scowl "Get lost..." he growled at the man. The man had a look of fear of his face before he ran away in fear of what Lex would do to him.

Lex walked through town with his hands stuffed in his pockets and he eventually reached an abandoned library. The door was missing from it and he sighed "Is this what I came here for? A run down shit hole?" he muttered as shook his head "I might as well check it out..." he said boringly as he walked in.

Once inside he heard laughter "Oh great someone else is in here..." he said as he walked all the way in and passed the guy reading the book and laughing. He walked over to a table and grabbed one of the books that was sitting on it and started to read it. He ignored the man as he read from across the room.

"Someone else entered... It was obvious, he is here... I found him, the Second brother... Lex"
Someone entered the place, someone with wishes of fear and ready to see destruction. "So this kind of persons... someone impulsive, someone that has no order... I am sure he forgot everything, or maybe he never knew anything" the masked man laughed when seeing the guy reading, he took the book with the words Anderson written and opened it staring at it a big while.

"Why would you read that, do you even know what it is about?" Marik moved, looking at the guy, his brother, Lex "This book, its better, you might like it more" Marik threw the book to the guy, he knew he was not going to accept it that fast, but maybe he could convince him to read it, and convince him of everything that the book says. That book had a lot of information, information that not anyone could understand.

Marik waiting for the gray haired guy to read the book, stood up and took out some knifes, playing with them, and playing with his mask "I need your help Lex... To look for Luxin... The third brother"

Lex didn't look up from his book as he caught the book that was thrown at him. He slowly brought the book down to read the title of the book. When he saw the name a quick image flashed in his mind for a second hen his eye twitched a bit. He now looked at the man and placed the book down at his table "I think you are mistaken... I have no brothers..." he muttered as he placed his hand on his head "Luxin... were.. were have I heard that name before?" he muttered as he shook it off and sat back down at his table.

He reopened his book with a sigh "Its not that I wouldn't be willing to help you but I dont help people without a free..." he said to the man with a growl. His mood changed from Peaceful to a mix of Confusion and anger "Listen, I dont know who you are but stay out of my way!" he yelled as he moved farther away from the guy before sitting down and reading again.

Marik took a heavy breathing and stood up with his hands in his pockets "You do have brothers, and you shouldn't be talking like that to your superior, and Luxin is our oldest brother, thats what this book says, and you should read it" the masked man gave a step closer to Lex, he then laughed. "You don't deserve to die, and you should help me, there is nothing free in this world, don't worry about that" Marik took the guy's cloth holdgin it tight and then took his mask off "Do you still don't remember me, look at me, at my eyes, is it necessary to explain you whats happening?!" the masked man putted down his brother, he then took the book and gave it to him "I insist, read it all" .
Marik sated down one more time playing with his knife and waiting for Lex to act.
