Just as everyone, who received a copy of Black Haven's findings, finished reading the research, the common people received a simpler version of the research. The version mostly have the general information while the advance and latter parts of the research were not included.
It was Black Haven Guild who distributed the simple version via Evo's orders. Only the higher echelons of each faction knew of the deal, so the people didn't know that their leaders actually paid for it.
With Black Haven's initiative to distribute the information, they would be viewed as generous and kind by the people.
People who were still undecided whether to try the Black Haven's Guild services gained courage and tried to be the first batch of interested individuals.
