A few hours later, Tavia leads you to the shaft she told you about. It extends into either way far beyond your vision, though you see the opposite wall on a few occasions. Naedragard looks down the shaft and whistles. "There's much more down here than I thought." Tavia points upwards, saying: "Up there is a nearly circular opening in the wall, on our side. The wall has a lot of cracks and offers good footing. Just make sure you don't slip. The fall would be ... fatal."
Naedragard waves her right hand: "Nah, I will watch over you ..." Half an instant later, she vanishes from sight, only to reappear about 100 feet above you, sitting on the edge of a ledge peering down. The scout and Xune fasten their equipment and start climbing. The diminutive priestess clings to the near vertical wall without much problem, observing the others in their ascent. Khalas cast a quick spell and steps into thin air. He quickly ascents even beyond Naedragard to check for enemies ... or so you assume.
The climb takes time, much like Tavia said, at least with those who do it the mundane way.
