My main question is in the title:
As the Logicians are not very popular among the Adeptus Mechanicus I was wondering which Mechanicus sects that would activily go out and route them out for purging?
Secondly:
And how would these Mechanicus sects interact with the Inquistion and Ministorum, as they don't like the Logicians either? Could it be three different groups (Mechanicus, Inquisition, Ministorum) hunting the same Logician cell without any of them knowing about the other groups' effort?
