Oliver is a 9-year-old boy, and the son of the famous Flame Alchemist, Roy Mustang. Throughout his lifetime Roy hid him from the public in order to keep him away from his work and the potential danger associated with it. But, Roy never let his son feel his absence. He used to find time between his devotion toward his country and his responsibility as a father. Even after all of these, he never talked to Oliver about his mother, so the desire of the child to meet or know his mother was never fulfilled. Before the Promise day, Roy sent Oliver along with his foster mother/aunt (Madam Christmas) to Xing, for their safety. Oliver returns to Amestris after few months with his granny (Madam Christmas) and decides to stay with his father in Central City.

After the death of Bradley, Grumman becomes the new Fuehrer of Amestris, and Roy gets promoted to a Major General. After the resolution of the conflict with Ishval, the environment of Amestris is seemingly peaceful. So, Roy decides to bring Oliver to the public eye and introduces him to his team first. But, within a few days a series of tragic events take away Oliver from Roy, and all of that happens just because of the child's desire to know his mother.

The story mainly revolves around Oliver and the legacy of Father. While expanding his empire, in order to achieve the stature of God, Father created four human chimeras who we were so strong and skilled that even his own children, the seven deadly sins were unable to face them in a battle. Father called them his four pillars, who expanded his kingdom in all the four directions. They captured many cities for him and massacred lots of people whenever he ordered. During there years of wars, there was only one battle where they had difficulty facing their enemy, and their enemy was not an army that time, it was a creature. The creature which was made of darkness, which refused to die. No matter how many times they destroyed its body, it was not dying. Even when Father, Lust, and Pride joined them in the battle, it was still impossible to kill it. Finally, Father found a way to calm down that creature before the situation could go out of control, and for centuries it never terrorized the world of livings like it used to.

The story is structured in a branch like way, where multiple stories take place and gradually the branches dissolve into some other branch. Eventually, all the storylines will dissolve into one single branch to give a proper resolution. Initially, the major storylines take place in Drachma, Central City, West Area, with some Xingese who are trying to strengthen their relationship with Amestris and with some Ishvalans who are fighting to make Ishval a free country. In the beginning, there are many flashbacks to Roy's past in order to give a proper background to Oliver and his parentage.

I have created some OCs which will increase eventually. Currently, some important OCs are:

Oliver (Roy's son)

The Four Pillars (Very powerful human chimeras created by Father centuries ago)

The unknown creature (identity and abilities will be revealed eventually)

The 12 Zhansi of Xing (They are the state alchemist of Xing, but they use alkahestry instead. They are the most powerful warriors of Xing. Moreover, the lesser the rank of the Zhansi, more powerful is the person e.g. Yin-Yang twins)

Marshal of Drachmann military, Prime Minister of Drachma, King of Drachma and few other characters associated with Drachmann King

Boris (Drachmann man who hates his government and helps Olivier Armstrong with spy operations)

IFF operatives (people associated to Ishvalan Freedom Front, which is trying to make Ishval a free country)

Some military personnel and new state alchemists (e.g. Cecilia Ingolfson, the splinter alchemist)

Each chapter is pretty big compared to a typical fanfiction chapter, so I am sorry for that but, I cannot shrink the size. Typically, each chapter is of 6500 words on average. Moreover, the writing style is unconventional due to which some of the readers might find it unpleasant, so I am sorry for that. Because of this, I would like you to follow the instructions given below to understand the conversation:
1. Anything inside " " is a regular conversation
2. Anything inside { } means the character is thinking
3. Anything inside ( ) is meant for information to the reader
The story is based on Fullmetal Alchemist whose rights are reserved to Fullmetal Alchemist anime and Hiroshi Arakawa. Many major characters are based on the anime
