To prepare for the divination, Ghost brought a book from the library to consult himself with, and from a room that appeared to be his storeroom of old, dusty and forgotten things—a seal. It was round and etched in on a tablecloth-like piece of black fabric with white thread and lines of aspects for seeing, hearing and knowing.
Compared to the jade seal Ghost gave me, or with the seal on JJ's coffin, it was a crude and simple thing. But if I looked closer, there were a lot of similarities to the jade seal. While the coffin seal was like a net, these both appeared to be more akin to looking glasses. Was the jade seal a divination seal, too?
In the middle of it, Ghost placed a saucer in which I shed a few drops of blood. After that went the hardest part, one for which Ghost needed to consult his reference material.
