Kirr has orders to remain in the capital but not to try and force his way into the citadel - the Governor will deal with this by way of dispatches to the heads of the Seven Houses.
The Governor will send a dispatch to the heads of the Seven Houses inviting them to a meeting in Seaward to civilly discuss the current situation, and indicates that he has critical information about the current crisis which he will share with whomever shows. He indicates that he understands that the nobles would likely prefer to meeting in Serien, and so would have he, but that is not possible as "the gates on the Caer appear to be broken."
