Featured in THE FIRST STORY:
CHAL
Chal is one of the Challenge World's magicians and one of its Challenge Makers. Before he met the player, he was a mischevious trickster and thus he was sentenced to a lot of hard work in the Challenge World, which disciplined him to have better behaviour.
In THE FIRST STORY, he represents single-completion challenges.
REP
Due to his hobby of working out giving him muscle and strength, Rep, one of the Challenge Makers, is the Challenge World's strongest gladiator. In the battlefield, he can stomp so hard the floor cracks into two and his hands can fan out tornadoes. But outside of the arena, he's approachable and won't hurt people as long as they don't mean any harm to him.
In THE FIRST STORY, he represents the most basic form of repeatable challenges.
FORM
Form was originally one of the Challenge Makers in the Challenge World. However, ever since he took on a job of being a math tutor, he is usually very busy that not many people know that he makes challenges.
He is very popular with parents enrolling for his tutorial classes on math.
In THE FIRST STORY, he represents Formula Challenges, a mechanic inspired by Quadratic Formula in Algebraic Progression by randomtuba.
