Chapter 212: The War that Decides the Fate of 'The Bridge' Part 15
Two days passed, and Kayn's group continued destroying one base of the Assembly of Freedom after another. Of course, they still went for it at random so that Jericho's Herald Guild won't be implicated.
Needless to say, they have the choice to not do it until Jericho's Herald Guild got accepted into the Assembly of Freedom. However, if they truly did that, it would make things very suspicious and would no doubt make Wesley think that the reason for the attack to suddenly stop is because the real perpetrators are currently waiting to be accepted to their side
Instead, what they did was that they ordered some men of the Thieves Guild Alliance that got into the Herald Guild to fake a pursuit of them.
These people already went through a thorough investigation and it was confirmed that they are members of the Assembly of Freedom.
