Reginald Denham

"No matter how many times I try to tell myself that it was either him or me, it doesn’t change the fact that…I. Killed. Him. And I couldn’t handle it, so I ran."

- Reg talking about Nilo Reginald Denham (Reg for short) is one of the Salem Four. He is an air mage and the brother to Callum. At a young age, he and Reg were abandoned at the gates of the academy. He since lived there until the beginning of the novel.

ASFS
Reg is one of the four witches to go to Salem. Though at first, he abandons his friends out of fear of never seeing his brother again. He soon returns after saving Ash and Florence from Sentinel Pierce. He then stays with the rest of the Salem four for the remainder of the trip.

After Florence's death and upon returning to the Academy, Reg decides to leave, deciding instead to live a "normal life for once".

Air Mage
Reg is an air mage and thus has the ability to bend the air around him at his will. This presents itself almost like the wind. It is noted that whenever Reg gets angry and loses control of his powers, hair and paper is disturbed in a similar way to the wind.

Reg is also described as one of the more powerful witches at the academy.

Callum
Callum initially appears to be the only person Reg shows any affection towards. The two brothers have a close relationship and are distressed whenever they think something may happen to the other. It is the possibility of not being able to help his brother that inspires Callum to go to Salem.

Ash
Ash and Reg have a strained relationship throughout the novel, with the latter being much more aggressive than the former. This comes to a head later on when Reg wants to abandon the plan to go to Salem, causing an argument between the two which leads to Reg hurting Ash. When Reg later returns, their relationship is not initially fixed, but they both later abandon their animosity. When they return from Salem, the pair's friendship is much stronger and Ash is saddened to see Reg leave the academy.

Florence
Though they do not interact much early on, Reg appears to approve of Florence and her friendship with Callum. He is one of the only people to have figured out that she is not a momentum, but a time mage. Their friendship only grows when he returns to the group after the attack on the Rainbow Bridge. Reg is extremely saddened at her death.

Mary
Reg and Mary do not talk much during the events of the novel, but they seem to reach an understanding. Reg is the one who recommends Tanner Webster as a way to get out of the academy.

Trivia

 * Reg is gay, as is revealed in Chapter 23.
 * It is implied that he has/had a crush on Ash
 * In the first few drafts, Reg was a much moodier character, who hated his brother, Callum. This was originally going to be explained as the result of a spirit invading his body, but was scrapped in favour of a much more likeable character.
