Calum Hood

Calum Thomas Hood is university student entering his 2nd year and he has cystic fibrosis and always brings an oxygen tank and nasal cannulas. When he and his peers were transferred to Auckland, New Zealand, they were staying in a creepy, old fashioned house. When exploring the place that night, something was glowing on the bookshelf. Luke accidently touched it when all of the sudden, he and his peers were falling down from the trap door to the underground. That's when they meet an old man who is the guardian. He is given the amulet of Wind which gives him the ability to make forceful winds from his hands. He is friends with Luke, Michael, Wendy, Troye, Collins, Shawn and Devan and temporarily rivals against Ashton due to his intimidating appearance. Whenever his powers are used, his pupils and irises disappear and his eyes become blue. He is the secondary protagonist.

Physical Appearance
He has short(head shaved) dark brown/black hair, brown eyes and tanned skin. His brown eyes disappear and turn blue when he activates his powers and he glows in a white color. He stands on 6 ft 1 and on average weight. He has to bring an oxygen tank and nasal cannulas along the way due to cystic fibrosis. As everyday wear, he wears a loose black t-shirt, black jeans and black shoes. He wears a blue bracelet. His sleepwear consists of a black tank top and black shorts and doesn't wear his amulet. He is shown to have a g-tube and a lot of surgical scars. Later in the series, he will have short, thick curly dark brown/black hair.

Personality
He is optimistic but can be shown a little frightened at creepy things like when he and his friends were out exploring the house at night. He is also shown to be arachnophobic which makes him afraid of spiders. Whenever he gets scared, he could cling on either Luke or Michael like a koala. He can also be really smart.

He can also be concerned like how Ashton is being distant from his friends. He is also serious about his past like how he got punched on the ribs and has to stay in the hospital for a few weeks. He is also really cute like how he wrapped himself in a blanket or how his nasal cannula got loose. He can act somewhat childish like how curious is he or how he insists on watching Frozen on Netflix. He also has the habit of waking up late. He is also squeamish.
