River Mist and Flask of Wine made a request to party as they were "helping" to guide them through the jungle, River Mist had lost his voice and he believed it to be on top of Firefinger. The party was originally hesitant to climb the tower but after Cindy Sandhole was grasped by a [pterodactal thing] and taken to the top. So the party scaled in order to save her.
