The world tour is over.

It ended abruptly and tragically, with deaths and hard decisions. After returning home to normalcy and opening their school to students once more. But amid the mundane, Jean Grey's life takes a sudden turn towards the bizarre. Her mental barriers begin to erode as she starts to experience strange visions... like a giant bird composed entirely of flames. To save themselves - and the world - will the X-Men be forced to strike down their own teammate?
