Pterafolk Nest

This level is 240 feet above ground. A ladder clinging to the west face of the spire connects this level to the one below.
Pterafolk elders inhabit this area. They’ve constructed a traditional nest that’s better sheltered from wind and rain. The southwest chamber is home to four elder pterafolk (13 hit points each). They spend most of their time tending their fire (which makes the chamber stiflingly hot and smoky) and carving grisly totems from the bones of their enemies.
When the pterafolk have prisoners, they’re confined to the eastern portion of this cave. Currently, there’s one prisoner: a male aarakocra named Nephyr. He hails from Kir Sabal and was ambushed by pterafolk while on patrol. His wrists, ankles, and beak are bound with rope, and he has no weapons. He knows that at least eight pterafolk live on Firefinger’s peak, but he has no idea how many are there now.
If the characters set him free, Nephyr is grateful. Before departing, he urges the characters to visit Kir Sabal and petition Asharra to perform the Dance of the Seven Winds. This dance, he says, is part of a magical ritual that grants nonflying creatures the ability to fly. Once back at Kir Sabal, Nephyr spreads word of the characters’ heroism. Characters gain advantage on Charisma checks made to influence the aarakocra of Kir Sabal from that point on.

Reaching Level 4

A 50-foot-tall chimney ascends to the pinnacle of Firefinger. The chimney contains plenty of handholds and requires a successful DC 8 Strength (Athletics) check to climb without gear or magic. At this height, any significant noise in the shaft alerts the pterafolk at the pinnacle to the presence of intruders.
