Hey @docwyattbeyond.bsky.social I was rewatching s3 ep 10, and in one scene we cut back to Cole finding this stone. Is it relevant in any way?

This set is peak. It is interesting how the minifigure looks like Kai, but is named the master of fire. Perhaps Ninjago Legends will be a series of shorts about previous elemental masters heroics, and in set form they are personified through the current master. So for the master of fire we have Kai.
