The Burning of the Adventurers' Building

A gust of wind and a concussive boom drew the party to the top of Lord Garrick's archer tower, where they saw the Adventurers' building on fire. It is a critical defensive point for the city: it captures every gate and teleportation in or out and relocates them to one fixed area. With it down, portals began opening freely inside the manor grounds.

Lord Garrick armed up, told the party to stay put, and teleported away toward the fire. He never came back before the manor fight ended. Nobody knows who set the charge, or whether the building was the target or merely the lock that had to be broken first.
