There are a few notes written beside each of the names listed on both the lists.
The notes indicated, what affiliation they belonged to, and the allegations these students had on them along with some other information. Then the Deans finally felt a sense of realization dawn on them. The students that were killed all had only one major common point.
They all belong to the Noble league.
Most of them, if not all of them are part of the Noble league families and even among them the largest percentage covered the low ranking families of the noble league. The core members of the noble league only included a certain ten families.
Based on the information the Deans secretly gathered, some of these ten families are the ones currently destroying the Vlachous bit by bit.
