(Prologue)

A newborn baby was sleeping in the hands of a young woman with a black and blue ceremonial robe. There were people behind her with the same robes and in front of her was a tall man about with jet black hair and dark onyx eyes. He was wearing a robe with strange markings and symbols.

Behind the man was a stone with a crack in the middle of the stone. This was the Font of Avernus. All powers of the Avernus come from the stone. From the crack, black ghostly mist was seeping. The man took the baby from the women and held it in front of the mist.

"You shall accept the powers of the Font of Avernus. Let the mist approach and wrap you in its welcoming embrace and accept it as a part of your existense. From this day, you are a part of the house of Avernus." The man chanted and started lowering the baby towards the mist.

Suddenly the mist started to reach for the child. It quickly embraced the still sleeping baby from below and then pulled the child to the pond from the hands of the man.

"What is the meaning of this, Lord Abaddon?" questioned one man in a ceremonial robe.

Everyone from the crowd was muttering and whispering to themselves.

"This is truly extraordinary." Muttered the now revealed current lord of the House of Avernus.

Then suddenly the baby was lifted from the mist and Abaddon took him and inspected him. There was a ghostly black colored mark on the back of the babys hand. That mark was too familiar for him to forget. It was the same mark that he had on the back of his hand.

Suddenly he started to hear voices that he only heared inside his head.

Voices called to him "The child is like us!" one yelled one. "He has passed over the limits of life and death!" called another. These were the souls of the previous lords that had inhaled the mist from the font.

In the middle of the yelling inside his head he started to smile. His newly born grandson had the same unheard compatibility with the mist as him. The mist's influence was so strong with him that his powers let him exceed the powers of life and death and become what no one else has achieved and what everyone wants. Immortal. Not just something some puny god or the 'Immortal phenex' has. No, true immortality that exceeds the laws of life and death.

'With the proper training, he can learn to use the abilities, He could even learn the most powerful ability of the Font of Avernus. The power to reverse time.' An ability which is achieved by only the grand elders and the most powerful lords of the House of Avernus.

'The most unnatural of all the gifts of the Font of Avernus, this power defies mortal understanding. What should hurt, instead heals; and what should kill gives strength anew. ' That is how it is described as.

The house of Avernus gains it powers from the Font of Avernus. Every member has inhaled the mist. The ceremony is that every new born baby shall be bathed to the mist. With that ceremony you are and will always be a part of the house. You can't join the house if you are not bathed in the ceremony. That is the recruiment for the House of Avernus.

Lord Abaddon gave the child back to the young woman. 'He will become my apprentice and will be my successor as the next lord.'

The woman quickly covered the baby with a cloth. And hugged the baby to her chest.

"Now thou shall name the child, and the new member of the noble house of Avernus."

"Issei, Issei Avernus" the mother said. In a quiet voice.

Abaddon smiled. "Issei Avernus! I welcome you to the house of Avernus!"
