He is a student at the magisterium, a book series that consists of magic, and if you use to much of an element you can turn into a devoured then the element would replace your soul. But Callum isn't just an ordinary mage in training, he's a makar, which means that he has the ability to control chaos magic and make chaos ridden. Though he doesn't have his own soul, he has Constantine Madden's soul/ The Enemy Of Death. So he can control the chaos ridden that Constantine created. 

Friends with Tamara Rajavi, Aaron Stewart, Jasper 

A young boy who was raised by mostly his mother due to his father being a lazy ass alcoholic. One day when he was six, his mother was killed right in front of him, after his mother was killed by his father, his father tried to kill him next, it wasn't a surprise due to his father's abuse. He was sent to an all boys Catholic school that he would be living for a bit, despite him being a girl at the time. After running away and becoming homeless because of a death, when he was 12 his life changed..

Humorous, polite, and troublesome

A twelve year old boy that only has a father due to Constantine Madden killing his mother in The Cold Massacre. What he doesn't know, is that after Constantine died, he pushed out Callum's soul and replaced Callum's soul with his, now Callum has Constantine Madden's soul. His father (Alastair) hates magic and doesn't want him to find out that he has Constantine Madden's soul.

Sarcastic, a lovely person to be around, and nice.

Abby from Asylum by Madeleine Roux!

Can be considered narcissistic sometimes but still cares and will still put other people before himself. 

Caring, cusses a lot, lonely, flirty

After losing and then bringing back Aaron be feels like a failure and a screw up and or a liar after making a promise he wouldn't bring him back to life. Powerful, he's able to put cities, towns, building, and even humans into the void of chaos because he is a makar 

Annoying, lonely, hopeless romantic

Humorous and Troublesome but otherwise polite and quiet
