The Grey Mist's base was located beneath a desolate rock canyon in the northern part of the Yiter Federation, within the territory of Nisi Kingdom.
The commotion here tonight instantly attracted the attention of many High Rank forces.
First, there was the Limit-breaking Annihilation Beam, followed by an explosion whose power almost breached the threshold of the Eighth Rank.
Even though Zero ultimately intervened to contain the power of the explosion, the intense Magic Fluctuation at the moment of detonation was still perceived by many High Rank Professionals.
After an investigation, the existence of a Mysterious underground base here surfaced.
At the same time, many Ninth Rank Mages recalled their experiences exploring the Floating City, as well as that forbidden name [Truth Circle].
