Carl and Donut confront Remex in the Swordsmen depot and discover Mordecai was wrong: Remex is neither a lich nor a boss, but a level-one soul leech capacitor and Miss Quill's bereft minion. By inspecting Remex and the floating soul crystal, Carl learns that Quill used Remex as a conduit to cast necromantic magic and siphon the souls of the dead into power for the Swordsmen. Remex is terrified, in constant pain, and begs Carl not to approach or blow him up.

As Carl questions him, Remex gradually explains the history behind the town's undead scheme. Featherfall wanted greater control over the Swordsmen and persuaded Quill to help cast a spell that would resurrect Remex as a capacitor, but the attempt backfired and killed Featherfall. Quill had planned this outcome, hid Featherfall's death with illusion and forgery, controlled the city elves through false divine visions, and used them to bring women into town so she could create krasue, increase soul energy, and build obedient lieutenants for a larger campaign.

Remex finally reveals Quill's true goal: she was completing the third generation of an heirloom spell called The Final War. The spell required enormous stored mana and a protecting army, and once finished it would unleash creatures across the Over City to kill everyone except the skyfowl, chickadees, and others specifically protected within the spell. Carl realizes that by killing Quill, he and Donut have stopped a genocide, but they have also interrupted a massive spell in progress.

The system immediately announces a new group event quest, The Fools Who Broke the Glass, warning that the failed spell will explode across a 45-square-kilometer radius in seven minutes. Carl, Donut, and Katia are named quest hosts, meaning they cannot opt out by entering a saferoom, while all other crawlers in the blast area have only a brief chance to escape. Mordecai directs Carl toward the Desperado Club, but Katia cannot use it, and Carl sees via quest chat that roughly eighty crawlers are now trapped in danger because of the blast.

Realizing the epicenter is the soul crystal rather than Remex, Carl refuses to flee immediately. He returns upstairs with Donut, retrieves Miss Quill's valuable Sheol Glass Reaper Case, and carefully closes the protective box around the floating soul gem in the hope of containing the explosion. With no way to know whether the plan will work and too little time left to run, Carl and Donut sit together and wait out the final seconds as Remex fades in the corner and Donut quietly admits she knows a dead friend is truly gone.
