Ikky recalled the conversation he'd had with the Grand Elder when he expressed his surprise at the primitive magical power system based on crystal cables within the walls. However, the old man's explanation was quite logical; aside from dwarves or the Vertrans themselves, it was rare for any other race to find one being in a hundred thousand with a metal affinity, let alone gem mana affinity and enough affinity to break the cables.

Therefore, these types of circuits surrounded by magically solidified stone were quite safe and cheap, compared to other, more expensive magical materials that corrupted easily over time or were not as good conductors of energy.
