Diadem chronicles the adventures of three teenagers from very different worlds. Score is a streetwise New Yorker, Renald lives in a Medieval world where she readies herself for battle, and Pixel is confined to a one-room world of Virtual Reality. But now they all exist in the Diadem, the circuit of all worlds where their awesome purpose unfolds.
