In Tockworth's Clockworks, Tixie's long isolation within her Smoldertown workshop had left her increasingly reliant on the arcane wards she'd built to guard it, chief among them an alarm keyed to a spoken password. Other gnomes mistook her muttering to herself for a mind speaking to people who weren't there, and when Mayor Kreem's militia failed to stop her mechanical transformation, her Shield Guardian turned them back before her Clockwork Constructs turned on the town itself. Weeks into the ensuing Lockdown, Igna told arriving Adventurers of Tockworth's sleepless outbursts, and the party glimpsed the truth themselves through the windows of the Motherlode, watching Tixie address "Poots" before rising to return to work.
Because Nessa Nina Quickpick Rumbauld Pennyluck and Tixie's old flame Azimuth broke into the workshop without ever learning that "Poots" was a password, they had no way to disarm the alarm they tripped the moment the vault opened. Tixie arrived through a Portal Spell in a surge of anger and fractured recognition, but temporarily lost sight of the two when Ragnum and Punmiri Tel-Phaeun cut the power in Turbine Heights. Nessa took the key to the fail-safe and turned off her automatons, escaping Tixie's Animated Armors right before they noticed the Rogue.
Tixie gave chase and caught Azimuth on the streets outside her own workshop, barely recognizing him as she blasted jets of steam from her mouth, and slashed him down with force-sword that had replaced her left arm. She followed Nessa to the edge of Smoldertown, where Ragnnum threw the key into the sea of lava below. The Dwarf fought Tixie alongside Punmiri, Slonk, and Yuzzik. Though Tixie nearly killed Slonk with steam breath, repeated blows nearly killed Tixie; as Punmiri's dolorous bell rang through her failing mind, she insisted her "apotheosis" was only hours from completion before dimension-dooring away toward the Overlook, cocooning her station in an iron shell.
Nessa was able to save Azimuth from death, and the party employed Yuzzik to stay in the Turbine Heights power station. The Goblin undid every attempt by Tixie to alter the city's layout, keeping the bridges down long enough to allow Igna to pilot the Apparatus of Igna to Little Lockford's centre. They tunneled underneath the cocoon, and found Tixie in a half-transformed state. The Security Overseer's body had become a battleground of wire and machine-logic, the line between woman and construct all but erased.
Punmiri finally ended the transformation with a single guiding bolt through what remained of Tockworth's organic heart, stilling the city's constructs and lifting the Lockdown at last.
