Eluvian's Links
It's very hard to determine just what exactly is going on in Reynard's mind and why he's doing what he's doing. For reasons only known to himself and not shared with anyone, he decided to hire Eluvian as translator, researcher, and overall source of solid information.
After all, when there is a new drug around, he needs to know as much as possible to create the perfect illusion of it. Even if that involves some weird shit with stickers (seriously humanity!)
