Dungeons and Dragons: The Saga Sister's Origin Story

For a Dungeons and Dragons Campaign, my friend and I created sister characters. This is the sisters origin story.

Acidel (Me) and Flare (My Friend) were born into a royal tiefling family. Flare was first born into the saga family. She was raised as a responsible and cautious girl and is always up for a new challenge. She does whatever it takes to help the people she cares for. The second born was there brother Malcius IV who would be the new aire to his father's thrown once he is old eenough. He is a strong and determined man who loves his sisters very much. However, on the subject of ruling the kingdom, Malcius's heart turns cold and bitter much like his fathers. His thoughts ruling are filled with wars and bloodshed, where souly rules all. Then finally the 3rd born sibling, Acidel. A curious and strange girl. Loves to laugh and have fun and has a kind heart for all living things. Unless, those things try to hurt her family or friends. Then she will do everything in her power to stop them even if I means she gets hurt. Much like her sister.
Flare is gone leavening her sister with many unanswered questions. Malcius is overjoyed with the the fact that now the thrown will belong to him, but threat spells great danger for the kingdom. Acidel sets out on a journey to find her sister and bring her back to save the kingdom.
