Lycan

"“They’re like a Werewolf, but they can change whenever they want to, not just on the full moon,” - Callum. Chapter 4: The Rumour"

Introduction
A Lycan is the sister-species to Werewolves. They share much of the same abilities as Werewolves, save for the fact that a Lycan has the ability to alter their shape into their wolf form at will, as opposed to being forced into it during a full moon.

Transformation
A Lycan can transform into their wolf form at will. The wolf form resembles a giant, two-legged beast with a wolf's face. This transformation, however, is extremely painful and involves the rapid elongation of one's bones and expansion of their muscle mass.

Any wounds sustained by a Lycan in their human form will be subsequently healed during transformation, as seen when Callum's broken leg is healed. As a result, any wounds taken on in the wolf form are exacerbated upon transformation back into the human form.

Strength
The wolf form of a Lycan can be extremely strong compared to their human form.

History
In 1890, the Slaughter of the Demons resulted in the near extinction of most Lycans. Since then, there are now only two known Lycans: Callum Denham and Joshua Hamilton.

Trivia

 * It is unknown how new Lycans are made, as the origin of both Hamilton and Callum's Lycanthropy is unknown.
 * It is possibly a genetic trait, as Callum was born with the condition.
