Yeah, there might not even be a gem, but there will eventually be a new quest. If the ever get to know who Pippet is searching for (sixth warden) in person, and we finally get the REAL QUEST from Swoopy in The Lost Island, there's a 1/3 of a chance that there's going to be no gem at all. A 2/3 chance of there being a gem from the quest is possible. Half of that chance might be an Astral Gem, another half being a Shadow Gem. Both elements are very overpowered indeed, but it seems like there might be one.
