Sensing he was fast losing the fight against an enemy cloaked in fog, Thurl Merosska, Lord Commander of Feathergale, attempted his escape. He dashed for a lone giant vulture perched on the edge of the spire's pinnacle and jumped into its saddle.
Quick thinking Sorrow, cast alter self and took on the appearance of Savra, the Feathergale knight who Vall had earlier convinced to leave the cult and return to her father in Waterdeep. Because Thurl was unaware of Savra's departure, Sorrow's illusion was successful and Thurl pulled her up on the back of the vulture which then took off and quickly descended into the Sighing Valley.
Testing his luck for a second time, rogue, Shadow threw himself from the top of the spire. Once again, a member of the Aarakocra pack, watching from below in the valley flew up to catch him. It was a messy affair and Shadow was injured slightly by the talons of the Aarakocra as it grabbed him mid-fall.
Zintra, still on top of the spire, and slightly dazed and confused by everything that had happened, took a minute to compose herself before heading to look through the telescope. She found that it was focused on a thin gully down in the valley. As she looked, she saw the vulture carrying Sorrow and Thurl land at the entrance to the gully.
Vall, oblivious to everything happening on the spire, decided his work here was done and began to make the long journey back to Waterdeep to collect his reward from Savra's noble father.
In the valley, Thurl explained to Sorrow (disguised as Savra) that he would have to tell Yan-C-Bin about his failure to hold onto Feathergale Spire. He feared that it may cost him his life. He asked Sorrow to accompany him and she agreed, but attacked him with acid splash as soon as his back was turned. An already weak Thurl was burned to death by the acid.
Elsewhere in the valley, Shadow managed to convince the Aarakocra to take him to Sorrow by the gully. He also asked them to collect Zintra from the top of the spire and attempt to find and persuade Vall to return to them. One Aarakocra delivered Shadow to the gully, whilst the other collected Zintra without problem. Another Aarakocra located Vall walking away from the spire and eventually convinced him to return to gully with them and help strengthen the party.
Once they were all together, they discussed traveling down into the gully, but the Aarakocra advised them to return once they were more prepared. They spoke of a great evil amassing beneath the Dessarin Valley, and as it was their duty to help stop this they would provide two Aarakocra to help accompany the party into the gully when they returned.
The party decided to follow the advice given to them and instead headed back to the spire to see if there was anything else they could find there. Sorrow gained the trust of the vulture she had ridden on and carried Zintra back, whilst two Aarakocra ferried Vall and Shadow back. Before the Aarakocra left they told the party they would position one of their soldiers beneath the drawbridge and that the party should report to him before they left the spire.
On the spire, Vall decided to take the telescope from its mount. Then the party began their descent through the spire, checking the rooms.
On the first floor, they came across the rooms of Savra and Thurl each of which contained large amounts of gold and feathered cloaks as worn by the Knights. However, Shadow, true to his roguish ways, took all of the spoils from Thurl's room for himself. The rest of the party became suspicious, and when he tried to enter a room on a lower floor they decided to try follow him into the room. Shadow beat them into the room, but was unable to prevent Vall from barging his way in and so ran out and into another room.
After clearing out the accommodation, the party headed down to the ground floor. It was here that Vall came across two initiates preparing food for the feast. They seemed more interested in inhaling the steam as some part of a ritual than acknowledging Vall's presence.
Across the hall, Sorrow and Zintra discovered another two rooms. One was a scant accommodation with beds and no other possessions in it, whilst the other contained weapons and armor used by the Feathergale Knights.
Back in the kitchen area, Shadow moved through a door onto a open veranda where he found two initiates meditating with what looked like a monk (Hurricane) who was levitating slightly off the ground. Seizing the opportunity whilst they were in a trancelike state, he threw two daggers at the levitating monk. However, he misjudged the monks connectedness to his surroundings and without opening his eyes, the monk caught both daggers, one in either hand then launched a counter attack on Shadow.
Cornered, Shadow attempted to dodge the Hurricane and dash from the room. He succeeded in reaching the kitchen, but only to lead the Hurricane and the other initiates in to the room. Vall and Shadow were now outnumbered. With some quick thinking Vall managed to convince the Hurricane that he was here for the feast. At this point Sorrow walked in after having cast alter self to look like Thurl. The Hurricane, unaware of Thurl's death, believed Sorrow's disguise and asked what he should do with the two strangers in the kitchen. Sorrow, still furious with Shadow, told them that Vall was to be trusted, but that they should kill Shadow.
With his life in danger, Shadow attempted to make his escape by heading out to the drawbridge with the Hurricane in pursuit. In the hallway, Vall's curiosity got the better of him and he pulled a lever on the wall. Immediately a battering ram, decorated with a golden eagle swung from the rafters and towards the drawbridge, narrowly missing the Hurricane. Shadow was not so lucky and was knocked to the floor and badly inured. He scrambled to his feet and began to run, slipping through the grasp of the Hurricane.
With his fingers crossed, Shadow saw his only chance would be to rely on the Aarakocra stationed under the drawbridge. He threw himself into the valley and was promptly grabbed and flown to safety, although now unconscious.
Back on the spire, the Hurricane and his initiates returned to their meditation leaving Sorrow and Vall to wander into the stalls below and try their hand with an aerial mount. Sorrow jumped on the back of a hippogriff, whilst Vall opted for the easier to handle vulture. Zintra also managed to mount a hippogriff and together they opened the stall doors and flew out of the spire an in the direction of the town of Red Larch.
In the Sighing Valley, Shadow was given some stern words by the Aarakocra who told him the next time he jumped from the spire the only thing that would break his fall would be the ground. They took him back to the drawbridge and left him.
Shadow made his way down to the stalls and successfully mounted the one remaining hippogriff. He launched from the stall, following the three small airborne dots, in the distance, that were his fellow party members
