These mountains are inundated with the magic of the Plane of Water, which has a weakening effect on Crucia, the Dragon of Air. Yet, she, too, radiates magic, much of which accumulates in the Crystal Depths. We drain this air energy, which would otherwise weaken Crucia's prison, and dissipates it within our forge fires.
Thank you, [%NAME]. There is some vindication in using Crucia's own power against her.
