In Tockworth's Clockworks, Igna remained sealed within her Apparatus weeks after the Big Little Lockford Lockdown, her rations exhausted and the vehicle's interior increasingly foul, when Nessa Nina Quickpick Rumbauld Pennyluck's hammering finally convinced her to open the hatch. True to form, she proved abrasive and immediately hostile, somehow recognizing Nessa from her thieving childhood. Despite this, she agreed to help, and freely admitted her wish to see her old rival Tixie Taffebeser Tockworth dead. The mage revealed the location of the fail-safe key hidden on the workshop's second floor, warned that Tockworth's Animated Armors were rebuilding broken constructs, and noted with some discomfort that Tixie had somehow restored Igna's own long-lost Shield Guardian, though without its magical amulet of linked Abjuration. Despite her willingness to share what she knew, Igna refused to abandon her Apparatus, rendering her aid useless so long as the city's bridges remained impassable.
When the party later atop Giant Lizards and a plan to bypass the bridges entirely, Igna agreed readily, driving her Apparatus across Little Lockford while the captured goblin Yuzzik held the Security Center's turbines against Tockworth's interference. She tunneled the vehicle beneath the iron shell rising around the Security Center, delivering the party directly into the heart of Tixie's final transformation. They ended her apotheosis, and for saving Little Lockford, Azimuth Andrea Almanac Caspian Kelshplotter was named the new Security Overseer.
After they cleaned up the city, Igna continued drilling upward through the tunnels toward the surface, carving a path that Nessa, Ragnum Ironknuckles, and Punmiri Tel-Phaeun followed atop their lizard mounts as they left the Deepways behind.
