With no knowledge of the Trials, Minerva is completely unprepared when she is sent to Arena 1. Out of 50 Trial Arenas, the first is the oldest and the most dangerous. In this game, power is key - a sorceress must save the people trapped in the Arenas before the monsters get to them. However, no one has ever come back from the Trials. In Arena 1, Minerva finds Camellia, a Plant sorceress who has long forgotten her Trial goals. Together, they must fight to survive in the horrid environments. Meanwhile, on Earth, Fire Queen Cerys is trying to cope without her Lieutenant. With a powerful Dark Queen hungry for revenge, she can only hope Minerva will return before war arrives. She sends Lily Claire, a human teenager, into Arena 1 to help Minerva. However, fighting for people they care about extends far past a Trial Arena. In this final installment of the Two Worlds trilogy, only one side will be victorious. Will Fire be consumed by the Dark, or will it burn strong and steady through the hardest of times?
