Thermo-Drill

The Thermo-Drill debuts in Golden Son as a Telemanus breaching tool—a meter-thick, two-meter-wide circular drill mounted on a battery—designed to punch through fortified walls and doors. Across the series it evolves from a single-use siege implement into a symbol of House Telemanus’s engineering ingenuity, repeatedly repurposed for daring rescues, boarding actions, and last-stand defenses. Its recurring presence underscores the shift from conventional siege warfare to the improvised, high-stakes tactics that define the Rising’s later campaigns.
