To Subvert Wizard Civilization, Me?

In the wizarding world where knowledge is power, everything can become the subject of research by wizards. Except for the "Old Gods", which is the only taboo.

As for my true identity, unfortunately, I am a favored person of the "Old God", a cultist among the wizards.
