Apparently Meshif was collecting a set of figurines of which this Jade Fugurine was the last missing piece. It is unknown how it came into possession of a monster
The jade figurine is supposed to be in fact a gimmic reference to the jade figurine treasure in what is to be considered one of the first computer games: Zork. This text based adventure game was developped by Infocom, a spin off of MIT en brougth to the market in 1982. Infocom was later bought by Activision.
