One of the first character backstories that I developed was the backstory for the game/stories protagonist.
 

Creation Process:
When starting my character backstories I decided that for each of them, before writing, I would plan out a list of topics/areas that the biography could include when I would go on to write them. To create this list of possible inclusions, I went back to the character profiles that I had previously created, as I had listed a number of different areas in those that I could write about.

The list for the protagonist's backstory is shown below:

Concepts/events for the backstory to include:

• Living as a child with only one arm (/reason as to why he only has one arm).
   

• Receiving the mechanical prosthetic arm from his father.
   

• Father’s disappearance/life without him.
   

• Continued life working with his mother and Leonard – going out to sea to fish.
   

• Events leading up to the game/story beginning.

However, I soon encountered a problem while writing this character's backstory. This problem is that an area of my protagonist's backstory didn't make sense/needed further explaining.
For my protagonist, I gave him the concept that in the game he'll have at least one mechanical body part, being a mechanical prosthetic arm.
However, the backstory to this arm, being the reason as to why the protagonist has it, was what I had left unclear.
I had some concepts for different reasons, but I was required to list a few and experiment with them to see what was more fitting.

The main two reasons that I felt could work were as follows:

 

• The protagonist, while out at sea on the ship his mother and Leonard worked on, was attacked by a sea creature, or a mechanical creature, resulting in the loss of his arm (it being bitten/cut/torn off).
   

• The protagonist was born without one of his arms.
   

• The protagonist was involved in an accident where his arm was crushed.

After experimenting with writing a section of the backstory with these concepts, I decided to go with the concept where the protagonist was born without one of his arms. I decided to go with this concept as our audience is 7-12, and I felt that having the protagonist losing his arm to a creature tearing it off/eating it might be slightly too morbid to include (even though its the backstory/biography and most likely wouldn't be mentioned, at least too heavily, in the game). Additionally, I didn't end up using the concept of his arm being crushed, as I decided that that could be a good reason for the father possessing a mechanical arm (and then also link that to him in other areas further in his own backstory).

While planning/writing the biography, I looked back to the research I had carried out during this project, and during my last project, that looked into what some biographies include, to see what possibilities there were for my own backstory to include.

The Backstory is shown below:

As a child Ace was no different from the other children that playfully ran around Litore island. He was as an active and energetic boy just trying to enjoy his childhood days like any other child. But although his personality was no different from the other children, Ace was treated differently by the others who inhabited the island, for he only possessed one arm since his birth.
Although this special treatment wasn’t to harm Ace, but to be considerate of him, Ace still felt the pain of being different to the other children and being left out from the other children’s games. However, it’s not like Ace was the only inhabitant of the island with a missing limb, as many of the adults had a missing limb due to their own circumstances.
But Ace still felt like he was seen and treated as being fundamentally different from the other children around him.
Due to this Ace would often rebel against others by attempting show that although he was different in appearance, he was still as capable as the other children. The first rebellious act he ever carried out was sneaking onto the ship his mother worked on, to prove he could be useful in helping her, and to show that he was capable of accomplishing what those around him could do.

Ace lived with both his mother, Amelia, and his father, Hugh, who both worked and lived on Litore Island. Ace’s father was an engineer like no other the island had ever seen, capable of creating machinery that no one could quite grasp, but often dealt with the inhabitant’s ship upgrades and repairs. Although he lived on the island with his family, he’d often go on his own journeys around the world. Ace’s mother, on the other hand, was a part of the islands primary market trade, being fishing.
Ace’s mother, due to ever frequent rebellious demands of her son, would often bring Ace with her while sailing out to sea to help her with her job. Many of Ace’s childhood days were spent going out to sea with his mother and the family friend, Leonard, who worked alongside Ace’s mother. Ace not only enjoyed helping his mother and friend out but also enjoyed the refreshing breeze that could only be felt when sailing the seas. It was much different to the breeze felt from on the island.
Although Ace wasn’t as capable as the others, he still felt at ease on the ship as he didn’t feel left out, since Leonard would always find tasks for Ace to do, whether swabbing the decks, readying the fishnets, or even controlling the ship.

But Aces life soon changed. On the day of his fourteenth birthday Ace’s father returned from one of his journeys from across the sea, and upon meeting with his son, bestowed him with a gift that would forever change Ace’s life. Ace opened his present, held within a large case, to find his father’s latest invention, a mechanical arm. A gift Ace could have never expected but had always desired. His father helped attach the arm to his son, connecting it to Ace’s nervous system. For the first time in his life, Ace had two working arms. His father continued tinkering with the arm which was now attached until Ace could control each of its movements without the slightest of thoughts.
Ace's mechanical fingers twitched with anticipation until his father was finally finished attaching the arm. For the first time in his life, Ace had full control over two arms, a feat that once seemed like an unlikely dream but was now a reality.
But Ace’s father still had one more present to show his son. Knowing that Ace had before experienced the problem of feeling different to those around him, and knew that even with a mechanical arm would still feel somewhat different, he finally unveiled his own arm. To Ace’s surprise, his father’s once normal arm was replaced by a mechanical arm that was similar to his own. His father explained that during his latest journey, he was involved in an engineering related accident, causing him to lose his arm, but also creating the opportunity to create a prototype mechanical arm, for the arm he’d wanted to create to for his son.
Ace felt a happiness that he’d never quite felt before. Now with a body similar to those around him, and an arm like his father’s, Ace’s sadness of feeling different had changed to a feeling of pride.

A year after receiving the mechanical arm from his father, Hugh left on another of his journeys, but this time with the intent on finding a rumored location at sea. The family never expected Hugh to be gone for too long, but to this day he has yet to return.
Moving ahead another three years, Ace and Amelia are still awaiting the return of Hugh, who is presumed to have gone missing at sea.
But although the family is without Hugh, life still moves on for both Amelia and Ace, with them both going out to fish on a daily basis to earn their living. And although his father isn’t with him in person, the memories of him and the mechanical arm that he created for him forever will be.
