Just a quick note: Olive’s mother has a lot of different names for some reason and as such it might be difficult to place her. Her names are: Golden Laurel, Amber Leaf ,Autumn Gem and Sapphire Joy. Considering that I don’t feel like authenticating any of these names, I’m going with Golden Laurel.
 

 
Name: Olive Branch 
Race: unicorn 
Parents: Golden Laurel and King Sombra 
Siblings: N/A 
Cutiemark: And olive branch surrounded by a red ribbon 
Sex: Male 
Likes: Magic, books and quiet moments. 
Dislikes: Crowds, other ponies and owls. 
Personality: Olive is very shy and quiet. He really ever opens up with his mother and his best friend Fang. He is the type to watch others play rather than participate himself. His magic is very strong but he rarely uses it because other ponies give him strange looks for doing so. 
Bio:His mother told him that his father used to be her best friend when they were foals but soon got corrupted by dark magic. He then took over the Crystal Empire and ruled with an iron fist. Despite his cruelties to others, he seemed unwilling to release Golden Laurel. His mother loved his father but she knew the darkness had won over him. After the curse was released, she later found herself pregnant with the kings child. She had to beg princess Cadence for protection throughout the pregnancy.  
Note: He rarely ever goes out without somepony else because he is constantly found hiding in dark corners alone because he’s scared of other ponies stares.
