The Western Realm is home to deities, divine beings, and demons, with an extremely complex social structure.
Some possess formidable travelling capabilities and have their own ways of gathering and disseminating information, many of whom also dabble in trading goods.
Awakening potions, awakening facilities, and the formulas for the awakening potions are easily marketable goods that can usually be sold out in one go, no matter the quantity.
These travelers engage in both legal and illegal activities, the laws of the Western Realm favor the interests of the higher demons, and many of the lawbreakers actually share values closer to human ethics.
The Red Leaf Society has rooted itself in the Western Realm and understands society extremely well, which is why they know many channels to use these travelers to spread messages and transport goods.
Since the profits are indeed high, many residents of the Western Realm are willing to get involved in this business.
