On Interesting Treasure, Effigy Vessel
This strange cup obviously depicts a Mabden who has strongly interbreeding ancestry with Karasu tengu. Perhaps his children commissioned this piece, for it clearly would not be something the man himself would commission.
It is difficult to know, you cannot ask the Mabden for now they are the endless hungry dead, and killing them forever prevents the questioning of their spirit. For now you will never know. Your only question is whether to keep this ancient crafted vessel or sell it.
Gold value: 8 gold.
