Due to lack of resources at launch, there wasn't really the means to build mana engines to support the land.  Therefore, the Taaldarax had to get creative and came up with an alternative that proves more flexible, if more personally taxing.

Copper wiring stretches through most domains and regions in thin trails. Very little of this is for electrical delivery past heavy machining and tool centers, which are limited and centralized.  These are for conducting holy magic in continuous, low delivery that emerges in tiny crystal stones and emits life-generating, calming, soothing light and also affords the city a natural anti-evil ward.  These run on the underside of bridges, on high ceilings, and as needed to distribute light.  A webwork macrame is woven to ensure that if one part is knocked out, most systems won't go offline as a result, as they reach through all tunnels in a twisted circuit.  These centralize back to the Monahven. The hidden ritual room serves as the core for the "power" system, among other things the settlement is dependent on. The core is in the most protected part of the city in a giant crystal amplifier settled in copper and silver, in a copper and silver plated room ritualistically arranged for amplification and cycling.  Once dailing a new Holy Bless can be added to the stone, which is then empowered by a rule of 5, then a rule of octaves; though the room also has an idle rule of polarity waiting to be applied.  That's another story.  This magnifies by 5^8, or 390625 times value while retaining it for directed slow release.

Ceremonial attentions are also performed in this room. The glyphs are designed for a long term and slow release through the copper that has high conductivity and natural association with Kion's element. The first Unahzaal, Arux Vignar, and Ronax station pillars by which the webbing spreads are augmented with matching glyphs.  While it doesn't reinstate the original spell, it reinstates the rules of five and octaves.
