From Introduction: Thaereian forces on Cularin have had to fall back, recently. While some of the Thaereians made it offplanet, many fell back to Soboll. The heroes of Cularin have quite the task ahead of them – they must infiltrate the platform city of Soboll and capture Major Kurth San, the base commander. Direct frontal assault is not an option, because of the number of Cularin citizens trapped in the locked-down platform city.
