Tang Country, Thousand Gold Pavilion.
The Thousand Gold Pavilion is the largest commercial guild in the Nine Countries; its financial and physical resources are comparable to those of a royal family.
The main Pavilion of the Thousand Gold Pavilion is located within Tang Capital, occupying the most prosperous area, only slightly less grand than the imperial palace of Tang Country.
This is still a modest choice by the Thousand Gold Pavilion to avoid suspicion; otherwise, with their wealth, occupying half of the Tang Capital wouldn't be a problem at all.
There's no business the Thousand Gold Pavilion can't do; as long as the reward is sufficient, they can nearly satisfy any request from anyone.
Inside the main Pavilion, the current Pavilion Master of the Thousand Gold Pavilion is sitting opposite a man wearing a Wolf Head Mask.
