In 2002, a tragic accident at the Large Hadron Collider caused a particle acceleration explosion which covered almost the entire earth. After that crisis, an estimate of five thousand people around the world had genetic mutations, meaning that they have superpowers. Then in 2009, six children with elemental powers were kidnapped by Senior Profesor Harold Karwood who experimented on them by putting them into stressful and challenging ‘prisons’. This experiment was called the Elemental Project or known as the Unknown Incident. In 2019, the children who became teenagers were gathered by one of Professor Karwood’s colleagues, Dr. Jenkins Wright who told them that the Professor was dead. The six of them started to work together to find out mysteries of the Elemental Project and the fate of the mutants.
