|“||Then didst the Builder lay down His Hammer, and take His Chisel to hand. Smoothed he the rough gem, and shaped it to His will. For each task hath its tool, and every tool, a task.||”|
The Builder's Chisel is a holy relic of the Hammerites. It was lost or taken from the Hammer Temple previous to the T1/TG mission "Strange Bedfellows" and Garrett is asked to retrieve it (on Expert difficulty) in addition to rescuing their high priest.
