Children of the Arcanas: Fire

Welcome to the land of arcanas,where your arcana(base magic) affects Everything you do. Now meet Rose, a girl like any other going to that magical high school with her adoptive siblings. Only problem? She's roomates with her ex-crush/enemy.
But things turn for worse when she gets attacked and placed under a dreamer's spell, with her roomate forced to take care of her then. Then a mysterious group of people shows up and manages to take ober the school, forcing it to play a game while locked under an empathical spell.
The rules are quite simple really. To find the group responsible for this by the end of the school year. Or even better, managed to kill them before they make a move. But be careful, guess wrongly and you and your roomate will be killed-- or in their terms, out. But their motive is quite clear. To destroy the rest of humanity.
