The silver lattice holding the Western Pass was failing.
Not because Nissa Tarvond lacked the endurance to maintain it, but because a pass is a geographical feature and geographical features can be altered. The 14th Legion's forward artillery battery, having calculated that the Order-domain barrier could not be breached by sustained bombardment, had stopped firing at the silver domes and started firing at the mountain ridges anchoring them.
The resulting rockslides did not break the silver field. But they broke the stone the field was anchored to.
Sera Myrvalis watched the structural failure through the relay board in the Command Center. The automatics were feeding telemetry from the pass in real-time, translating the mass movement of Korthane infantry and the geological collapse of the ridgelines into amber pulses on the display.
