The Day I Saved Your Ass

Scarlett 'scar' Amor is the leader of the 'semivir marinus custodio' which is translated from Latin to 'The half-marine Guard.' They are a species of mermaid that are called 'Custos Militibus'. They are the type of mermaid that do not actually turn into a mermaid but has the same powers of normal mer-people. When they turn the age of 18 they have to decide if they want to go through the ritual known as 'purificationem spiritus' to get their powers and become a member of the guard. Scar is the daughter of the General of the Semivir Marinus Custodio, and when she turned 18 she went through the ritual she gained four new powers: Force-Field Generation, Vibration Manipulation, Pyrokinesis and Hydrokinesis. She is 1 out of 3 Custos Militibus that have more than two powers and was straight away made the leader of The Guard. Scar is tasked to find the son of the best warrior (Tiberius) in the past 100 years before Rebellium gets to him first. Ethan Clarke is the son of Tiberius Argenteus the best warrior in the past 100 years. Tiberius left the guard to live in the normal world, among the humans when his son was one year old. His wife at the time gave birth to him and his father raised him in Lorem Militibus until his mother was killed in battle against Rebellium. Tiberius then took his son and left Lorem Militibus, but as protocol says, 'anyone who is too leave the Semivir Marinus Custodio is to have their memories wiped of Lorem Militibus and the Custos Militibus people.' Then her job is to keep him safe and train him long enough to go through the Purificationem Spiritus ritual and become a member of the Semivir Marinus Custodio.
