Deep beneath the city walls, a large underground chamber was filled with countless magic circles. Mages stood around the formations and carefully controlled the flow of mana through them. Their faces were serious as they continued maintaining the huge spell array that kept the barrier around the Imperial Capital active.
Large piles of mana stones were placed around the chamber. Some had already lost most of their light, while others were being replaced by servants and mages whenever their mana became too low. The amount of mana being consumed was enormous, and the constant operation of the barrier required a steady supply of both mana stones and skilled magicians.
At the center of the chamber stood a huge core structure that connected all the magic circles together. Lines of light continuously moved through it and spread toward the pillars buried beneath the city walls.
The entire system was overseen by a Saint Rank Magician named Edrin Valmont.
