From publisher blurb:
A Ready to Roll module for Echoes of the Ferrochrome Empire, a Forged from GRAM saga where a conquering empire wasn’t defeated, but slept and waited for a new challenger to wake them… and then someone did.
Civilization has ended in this world, perhaps even more than once. The former conquerors -- known now as the Ferrochrome Empire -- enslaved the continent in its entirety before retiring to their tombs to wait for a worthy challenger to the throne. Life began again; civilization spread again. The people had settled in their ways as a medieval-esque society, enjoying their new lives… but their time to shine could be limited by those who formerly held the spotlight.
In this episode, the current inhabitants of this world accidently awaken the rulers of old. This sparks a war of old ways versus new ways, where the long-dead Empire awakens to show the current kingdom how best to rule. It’ll be up to a small band of heroes to stop this movement before it spreads.
