Mana chambers were very simple in both name and function. They were the most common yet fundamental facility in the Magic Tower. Every mage that was Class 4 and above had one installed in their apartment, and it was used for everything from making items out of alchemy to testing new spells.0

However, the mana chamber that Leonard asked to use was special. There was only one in the Magic Tower.0

I think they said that not even Elders are allowed to use this room without the permission of either the Chief Elder or Towermaster. 0

The average mana chamber was integrated with twenty to thirty times more mana than the natural amount existing in the air. If a mage wanted a higher capacity, they had to go to the upper floors. Esther’s room, for example, had a little less than fifty times the natural amount, while the Elders probably had over a hundred. 0

However, the special mana chamber that was only readily available to the Towermaster and Chief Elder was integrated with close to a thousand times the amount of naturally occurring mana. It was so dense that formidable mana cultivators and mages had trouble even breathing inside it.1

This world already has several times the amount of naturally occurring energy found in the Central Plains, but to think that this room has nearly a thousand times that… it makes the Enchanted Forest...0
