"Nice," says Deren, impressed, "But doesn't that just mean they'll be back to fight us later, maybe when we're in worse shape?" he asks as they walk forward.
He keeps his eyes in motion, scanning the surrounding areas.
"If you act quickly, you may be able to destroy them before Pelor's power fades. I must stay distant, though, or the power will break." If the group takes that course of action, Aeron will follow behind them (carefully staying at least 10 feet away from the turned undead).
"Crawling into the tunnel to confront them in such cramped terrain would be far worse than fighting them out in an open chamber such as this one. Any more caltrops to impede them returning through that tunnel entrance?"
Instead of crawling into the tunnel after the vanquished ghouls, you opt instead to move into the eastern portion of the chamber. Although a few of the niches still contain remains of those interred there, in appears as though most of them were never used before the fall of the Moathouse.
Exiting the chamber through a grandly decorated archway, you make your way down a long corridor. Eventually, the passage splits. It continues straight into darkness to your left, and descends down a steep flight of stairs to your right.
Turning left, you continue down the corridor, and soon find yourselves at another branching path. Straight ahead of you, at the limits of your light source, you can see a door set into the wall, while another passage splits off to your right hand side, heading in a southeastern direction.
