Although the Key of Transformation, most adept at Space Magic, has fallen in the chaos of the Capital, the Divine Knowledge Saintess also vanished after resigning in disgrace.
Therefore, neither the Kingdom nor the Church has made significant progress in the assault on the Black Gate, evident by the infiltration even in the Holy City near the Saintess selection.
Among the Keys of the Door, the Black Dream Key is considered an especially low-profile and mysterious member.
It is said she doesn't kill her enemies, but those who have seen her true face fall into an endless dark dream from which they cannot awaken. Although their souls do not disappear, they are as if eternally asleep, plunged into silence.
The Church even established a specialized medical care facility to house those victimized by the Black Dream Key, hoping that one day they would awaken.
