Moving with a little cunning
A day went by like that while Matthew waited for everything to water down.
The voice of that explosion, those killed, and everything concerning him and his movements had to spread within the city, as his plan started from there. If they did not do so, then he would go and kill some more so that the plan could start properly.
The first thing was that he needed those guys to send guys after him, for surely they were already somewhat suspicious of his presence here.
And his wait came soon after when something strange came out to the general public of the City of Clans: Several people who were previously expelled from the city and who are enemies of the City for causing chaos and killing members have infiltrated. The individuals have been identified as Matthew Dietrich, Albert 'The Ruin', and Isla Moore.
In the news, Matthew Dietrich had murdered numerous people in the City for no reason, and Isla Moore was with him on that.
