From the introduction:
Artifices of Quartztoil Tower is a mid-length adventure which should fill 3–5 average gaming sessions of 3–4 hours.
It begins in the marketplace or main square of a town when the calm, peaceful day is interrupted by a hulking golem trouncing through town, smashing objects, and attacking townsfolk.
The party witnessing this should intervene and stop the rampaging golem with combat or by luring it into a nearby warehouse to trap it so it can be damaged and, eventually, destroyed by the town guards.
When the party examines the golem’s remains, they find bones encased in the metal armor and the name 'Quartztoil' written in gnomish script. The town guard explain that this is the eighth construct they have encountered in the area in the past six months.
The party can then go on to investigate the name 'Quartztoil', leading them to learn of an old, gnomish, aspiring artificer, Penaral Quartztoil, who had a lab and workshop in a tower in the nearby mountains, but who has not been heard from for close to a century.
