“Hundred years ago, the earth was on the brink of destruction. Three genetically-enhanced test-tube babies were created by the United Nations Aero-Space Force to be the leader of a project that aimed in searching for other planet suitable to sustain human life. They were your father, his brother and sister.

  “The project known as ‘The Red Mars Project’, aimed to colonize Mars. The three of them and the colonizers, consisted of 100,000 peoples from every nation on earth succeded landing in Mars and discovered alien life forms. It consisted of two forms, Kudlak Bacillus and Krusnik Bacillus.

  “The colonizers and your father’s sister, Lady Seth which was the Head of the UN Science Department examined this alien. Regardless of its unique name, their form was not much different from humans in general.

  “Kudlak Bacillus were replicated and distributed to the other colonizers, allowing their bodies to survive the Martian environment and live up to 300 years. The colonizers which had been infused with Kudlak Bacillus were then called ‘Methuselah’.  However the Krusnik Bacillus proved to be difficult to grow and attempts to reproduce more were unsuccessful.

  “Some time after the discovery of these alien life forms, accident in a project left Cain, Lady Seth and the other colonizers near the brink of death. In an effort to save them, Lady Seth injected them with the Krusnik Bacillus. This initially killed them, but after some time, Cain and Lady Seth came back to life, suggesting that only the genetically-enhanced individuals were capable of utilizing the Krusnik Bacillus. To prove it even more, she also injected the Krusnik Bacillus to your father and he survived.

  “With Kudlak Bacillus infused in their bodies, the 100,000 colonizers which consisted of people from every nation,  wanted to gain the possesion of the Kudlak Bacillus to their own country. Then the war broke out on Mars, known as the ‘Martian Civil War’.

  “Being one of the three people who was genetically ehanced, your father hated the human who made him the experiment of this project. Later, the colonizers who then known as the Methuselah turned against your father and the other leader of ‘The Red Mars Project’. Cain and Seth were in state of urgency and accidentally activated the power they got from the Krusnik Bacillus.

  “Their power were the Nanomachines. Nanomachines in their bodies, made them superior from the Methuselah. The Methuselah were dumbfounded by the fact that the Krusnik Bacillus were more powerful than them. The Nanomachines inside the genetically-enhanced human were triggered by the blood of Kudlak Bacillus, enabling a massive use of power.

  “Feeling enormous power when he activated his Krusnik Nanomachine, Caine fused with his  Krusnik Nanomachine 100%. Meanwhile, King Charles and Lady Seth didn’t fuse with their Krusnik Nanomachine 100%. They were succesfull in fighting the Methuselah by drinking their blood. Some Methuselah then fleed to Earth.

  “Didn’t fully aware of the danger resulted by Caine who had fused 100% with his Krusnik Nanomachine, your father and his sister influenced by Caine decided to explore other planets that suitable to sustain human life. He said that they shouldn’t forget their main mission to help the human on Earth.

  “But, you father refused to join them and returned to Earth to live his life in a normal way. Meanwhile, the colonizers who had been infused by the Kudlak Bacilus, developed vampirism symptom when they arrived on Earth. Due to Earth’s closer proximity to the Sun, they couldn’t expose to the sunlight. Their body mutated and forced them to consume human blood. The solution that they thought they had found was causing new conflict. A lot of human killed by the Methuselah. This was ‘The Dark Ages’.

  “Lady Seth finally realized that Caine’s plan to colonize other planets wasn’t for a good intentions. Lady Seth then asked for your father’s help to stop Caine. Your father then headed towards EXO Planet, the planet that Caine would colonize next.

  “Knowing that some people in EXO Planet had special power who were born from one sacred tree, Lady Seth examined them. She then found out some similiarities between the Methuselah and people of EXO Planet. Turned out, Kudlak Bacillus was eventually the origin of people from EXO Planet. Their great-grandparents created the Krusnik Bacillus in order to find new power source but it backfired and consumed them. Bent on destruction, they sent the Krusnik Nanomachines throughout space and eventually crash-landed on Mars. 

  “Caine’s plan was to colonize people of EXO Planet and to consume them for his Krusnik Nanomachine. Lady Seth and your father tried to stop Caine. But Caine who had already fully infused himself with his Krusnik Nanomachine made a chaos, hurted and killed whoever disturbed his plan. The people of EXO Planet then helped King Charles and Lady Seth to stop Caine. Caine wounded pretty bad. He then fleed and crushed all the spacecraft so they couldn’t go anywhere.

  “Your father and Lady Seth stayed in EXO Planet for a while. There King Charles met Queen Victoria and fell in love with her. Then they got married and you were born. For a few years, they had a good relationship with the people of EXO Planet. The people in the EXO Planet respected and appreciated them for not setting them as ‘food’ like what Caine did.

  “Caine who had fleed survived and planned for revenge. He looked out for the Methuselah on Mars and consumed them for his Krusnik Nanomachine. He then traveled back to EXO planet to kill King Charles and Lady Seth. Caine thought that he could easily kill other beings beside his own kind, Krusnik individuals.

  “Because your father and Lady Seth didn’t often consume the blood that powered up their Krusnik Nanomachine power, they were overwhelmed by Caine. Your mother who was the origin from EXO planet, sacrificed herself so that your father could power up his Krusnik Nanomachine to defeat Caine. A massive battle happened between your father, Lady Seth, Caine and the people of EXO Planet. In order to defetat Caine who had fused himself 100% with his Krusnik Nanomachine, you father did the same thing. They succeded on defeating Caine, but your father was killed. Lady Seth injured pretty bad and dissappeared from EXO planet.      

  “Before the battle, I was entrusted by your parents to take care of you. They worried that you may carried the same Krusnik Nanomachine as your father, Lady Seth confirmed it by examining you directly. Then they made a plan to hide you and the fact that Krusnik Nanomachine is running in your blood. I brought you here and wiped out your memory because your parents wanted you to have a normal human life.

  “We didn’t know, was it safe to brought you to Earth because the Methuselah on Mars fleed to Earth, too. That’s why your parents arranged these 12 young man who has special powers from EXO Planet to be your guardian. We also didn’t want you to activate your power or at least until you’re old enogh to use it.

  “It should be fine now, but hearing what Kris said few days ago about the vampire who attacked you at School surprised us. We thought that Caine was killed.” said Kate after explaining her family historu.

  “Moreover, this is about his descendant.” added Kris who still remembered what the vamapire told him at school that day.

            “Yeah, right.” responded Kate.
