A small lair adventure - just 11 rooms, set in the Fallen Empire setting I've made a few comments about. The party can elect to explore a destroyed war machine of the ancient world, recently brought down by noble infighting.
from the introduction:
Resolute and alone atop a limestone knob, the verdigris covered remains of an Imperial municipal siege unit, a bronze colossus, the ‘Akolouthos’, 3,200 years old and first operational in the service of the Imperial legions, surplused to the Styllus family until only three years ago. The Colossi was the bastion of Styllus dominion over five hundred miles of prime Central Province vineyards and grain, but without it the family has been nearly run under by their neighbors, the Comizius clan. Largely intact, the Akolouthos may even be operational. If the war machine can be repaired or salvaged, the Colossus’ value is immeasurable, and even if destroyed many valuable bits of its arcane workings a likely to be salvageable from the almost intact Colossus.
