Your craft is destroyed by an unfamiliar vessel and you're forced to land on an island that has been abandoned and Barred by your people. The events that follow will lead to questions about power and responsibility, to secrets thought buried and to the source of what could be ultimate realisation of the arts of the Shapers.
