City of Hope, Core walls, Hidden Underground Facility.
Deep below the blood red magic tower belonging to the Guardian of Humanity was an underground facility where the dark side of the city happens.
When there is light, there is darkness. There is no person in this world who is pure light, not Rezen, nor the Guardian of Humanity.
In this underground facility, the dark side of the city was ever-present. Horrible things that would make one question their morality happen here.
Inhumans experiments, human sacrifice, torture, anything one would expect can happen here. As cruel as this place was, it was a crucial part of the city.
Theories were tested here, making the people more knowledgeable about magic. The magic cannons used to protect the city walls are charged here sometimes using human batteries, constantly draining the martyrs' mana. Humans were experimented on and turned into non-humans, to be used only when the city is fully on the brink of collapse.
