You climb up to the first floor using the remnants of the ladder and crumbling masonry. The wooden floor, creaks and groans under your weight drawing some complaint from the bugbears below. Up here, there is a door in the west wall, leading outside to the top of the wall, and arrow slits in the north, east and south walls. You continue your climb, using rickety bits of ladder to the top of the tower.
On the roof there are crumbling merlons all the way around. The wooden floor is in an even worse condition that the one below. From up here you can see into the walled off basin below the cliff. Stairs carved into the cliff face lead to a lower section of ground that forms natural dock. Four men sit around a fire and a small boat is moored to the dock.

Errol's flattery seem to be taken well by Drosnin, she sits you down on one of the pews and with her full attention explains some history of the underground city.
"The realm of Besilmer was something rare: a dwarven kingdom built on the surface, with its strength measured in fields and pastures. It prospered for a time but was plagued by trolls and giants. The dwarves were obliged to build a stronghold underground, carving out the fortress-city of Tyar-Besil a century after Besilmer's founding. Unfortunately for the dwarves, the realm collapsed after its king and founder died in battle. Most of the surviving dwarves sought safer lands. The dwarven city beneath the Sumber Hills was abandoned by -4160 DR and then forgotten.
"Many believe that Tyar-Besil was built upon a drow temple, and fools believe that was the cause of their downfall, but the drow rose and fell, as the dwarves after them, because of their ignorance.
"Little did the dwarves or the drow know that they were building above something much more powerful, it was their failure to venerate this great power that truly led to their downfall, had they worshipped the Eye - or even on of the Eye's princes, they would be so much more. They would have led the world to the purity of the elements, not this abominable chaos we call the world."
After her history lesson, she holds Errol's shoulders, "Perhaps you can join me as an acolyte, but first you must prove yourself to Jolliver."
