I'm going through this book to prep some foreshadowing about how Gauntlight works, and I wondered about its power source being centered on the 4th level - after Lasda is removed from Lasda's Lament, Volluk is defeated and the Forever Stairs are opened, what's to stop any of Belcorra's minions "re-powering" the lighthouse from another similar Gauntlight location within one of the various chambers where the blue light runs from floor to ceiling within the lighthouse structure? I'm struggling to suspend my disbelief that there would be no attempt to re-activate Gauntlight on the enemy side between the time the adventurers make their way into the training grounds and the time they arrive at the final level. Would love a second opinion on the various ways that Gauntlight is powered, and why Belcorra would turn her attention elsewhere after the finale of Ruins of Gauntlight.
