But at the moment, it is unknown how many pocket realms are in Ninjago alone, never mind the other 15! Personally, I think we do have a clue at two more realms; Clutch Powers' world and Knighton. Clutch Powers is confirmed as having visited Ninjago, and given how his world has clearly different rules (namely Lego bricks, creation sparks, people pulling themselves apart and so forth) I think it's safe to say his world is its own, separate realm. As for Knighton, the Fortrex has images of Eris and the Lion Temple in its holograms, indicating it's part of the Chima canon, and therefore part of Ninjago canon.
