Some people could ask the question.
How can I be this sure? The answer is simple: they were a major organization in the novel.
In a world with reverse harem elements, having an organization fighting for "liberation" wasn't out of place. It was almost predictable, a staple of the genre. But at least the author had the sense to craft them as villains rather than an idealistic faction. The Cloud Heavens Sect wasn't about freedom; it was about power dressed up as virtue, indulgence wrapped in rhetoric.
And at the heart of it was her: Lira Vaelan, the Silent Thunder, the sect's rising star and its greatest manipulator.
