The Grand Yin Sect's headquarters was located directly opposite the Nine Dragons City God Temple, in an inconspicuous building hidden within a narrow alley. From the outside, it seemed very unremarkable, but once inside, one would find that it was actually quite spacious. Contrary to Xiao Buli's expectations, the decor here was extremely simple and austere, with monstrous sculptures surrounding a massive altar as its sole adornment. These features lent the place an added air of mystery.
Members of the Grand Yin Sect were all dressed in plain colored magical robes of black, white, and gray, creating a solemn and respectful atmosphere. Since everyone's Prestige here was essentially indifferent, the sight of NPCs with their brownish-red names gave the illusion of walking into a den of monsters.
