With the expedition regaining some semblance of civility, Claire and the rest took a moment to analyze the situation. Although there wasn't much information to work with at the time, Revna suggested delaying their departure a few minutes, mainly to observe the course of action of the most dangerous groups present.
The Poisonous Ghost Heart Sect had remained isolated from the other groups, although it was hard to tell if it was by choice or because no one dared to approach the group that had a reputation for poisoning others to death for mere entertainment.
The Unattainable Summit Sect was actually the first to leave. They didn't say a word to anyone, ignoring everyone who tried to approach them for cooperation. It seemed it wasn't just their leader who was a person of few words.
