I understand that in the description, the killer is portrayed as an intellectual professor from a prestigious faculty, because he uses complex formulas and even surpasses the class monitor. And where do intellectuals study? In Academies, of course. Stormwind, for example. But none of the clues I found using this method worked (I don't even know how it was possible to provide so many clues for the ascetic profile of the Phantom), which means I don't understand the principle by which the Master creates clues. Therefore, it's not worth basing my reasoning on them, so I abandoned this approach.
For example, returning to the clue about the Phantom, we can theoretically assume that the Master translated his nickname into Russian and then looked up its meaning in a dictionary, see http://ru.wiktionary.org/wiki/%D0%BF%D1%80%D0%B8%D0%B7%D1%80%D0%B0%D0%BA_%D0%BF%D0%B5%D1%80%D0%B0. Again, the synonyms for "Forgotten Phantom" actually fit. After all, we haven't solved that clue yet, have we?
What does that mean?
So, do you still want to get to the bottom of the truth or just "quickly" finish the game?
I already called him a mafia member, why should I shout anything else?
