Naturally, the Lightning Manor very quickly noticed what was going on, and they couldn't be any happier about it.
The Tower of Climate wasn't putting too much pressure on the Judgment Palace, but they were definitely applying pressure. The Judgment Palace needed to maintain a constant stream of Mages that defended its territories.
Of course, that included Ancestral Mages, and since the Ancestral Mages were also desperately needed at the frontlines with the Lightning Manor, their absence was very noticeable.
However, the Lightning Manor couldn't afford to send all their people to the Judgment Palace right now since their forces had already been reduced by quite a bit. The other two Empires were still applying pressure to the Lightning Manor.
So, they decided to use this opportunity to recover and strengthen their other frontlines.
