(~1,200 Years Ago)
The third Council attempted to claim sovereignty over Nod in terms that exceeded their mandate. The specifics vary by account, but the consistent elements are that the Council began regulating transit through Nod's gates, imposing tariffs on the roads leading to other Domains, and arresting Scribes and anyone of significant power who refused to submit to their authority.
Nemo responded. The details of the response are not recorded because there were no survivors among the Council members to provide testimony. What the Chroniclers have is the aftermath: seven bodies arranged in the Council chamber in positions that suggested they had been killed simultaneously and from within, as though the room itself had decided to reject them. The replacement Council was seated within a week. Its first act was to formally acknowledge that Nod's gates and roads were not Council property and would remain open to all.
The Purge established the boundary between Council authority and Nemo's tolerance. Every Council since has tested that boundary carefully, if at all.
