The Gatehouse
You stop on your descent, figuring any closer and you would be within range of either long bows or fireballs and survey the ruins of the gate house below.
Originally there were once two towers with what must have been a massive gate sandwiched between them. But the western towers appears to have fallen down completely. And the gate lays on the ground. The eastern tower is still clinging to something resembling life. There are visible gaps in the walls of it's three floors. And there are marks of what must have been fire damage running up it's southeast side. The eastern wall beyond it has partially collapsed, leaving a large gap in the fortifications.
The air is incredibly still. Not even the water in the lake is making a sound as it laps against shore. You can see what appears to be a light the upper parapet Area 8 on the map for the Gatehouse. But whatever it's source, it is below the rim of the wall. Like someone has put a lantern on the floor up there or some such.
Several ways you guys can approach here. The main gate. Climb over the rubble of the west tower or the gap in the eastern wall. Flying is of course also an option for you guys. Let me know if there are questions and how you may wish to proceed. Thanks
