The Eternal Vigil

Sera Grenn discovers a hidden Progenitor tunnel beneath Ironworks debris using a resonance scanner, revealing a two-tiered construction system unknown to thirty years of surveys.

As the expedition passes through the Ironworks ruins, an unnamed veteran tells Asha val Mechas about the three thousand who died there during the civil war cooperation lessons - integration failures that killed through friendly fire and miscommunication.

The 200-person expedition departs New Haven through the eastern gate, with Cael at the head and Petyr beside him as always - a conscious echo of the Book One march toward Valtherion thirty years earlier.

Sera presents her underground survey data to an emergency council session, independently verifying Damien val Torren findings with Scavenger instruments.

Cael visits imprisoned civil war leader Kael Thorne at the Western Fortress, who has been counting seal tremors through the Progenitor stone walls for eleven months.

Sera Grenn conducts an unauthorized survey of the Progenitor tunnels beneath the Deep Forge Memorial with Scavenger engineer Asha, discovering active conduit lines pulsing eastward at 1.7 Hz with elevated temperatures.

At a priority council session, Damien presents twenty-two years of seal degradation data with clear visual charts. Daven challenges the diagnosis as single-source interpretation lacking independent verification and proposes a formal six-month study instead of emergency measures.

Petyr arrives at Cael's quarters without knocking - a signal of extreme alarm - and presents the warm stone fragment. They immediately visit the basement archive of Damien val Torren, the alliance's long-ignored seismologist, who reveals twenty-two years of unread data: conduit temperatures are...

Petyr, the devoted keeper of New Haven's memorial garden (32,411 names), discovers that the stone at Tomas Grenn's section is warm to the touch and bears a new hairline fracture radiating heat he recognizes from the seal ritual tunnels thirty years ago.
