The elemental sigils around the Monster World never had an observable origin... until now. The Epic Zynth was the first monster to set foot in the Dreamscape, as well as the Magical Nexus, leading to it's nickname: The Mon in The Moon. It uses invisible ink to draw on it's black-light bulb backside, and we've seen many drawings of baby monsters, leaving us to question if it's actually a Wublin or not... but we still think it may have been involved with the creation of the sigils.
