The16RealmsOfNinjago

I think that one of the realms could be the Digiverse. In Lego Ninjago: The Visual Dictionary, it says in the TV series part of the book in the season 3 section (Rebooted) these exact words: "The Ninja enter the digital 'world' of the Digiverse to fight the Digital Overlord". Realm is another word for world, so that makes me quite suspicious. Also, whoever said that Bionicle might be a realm, that could be true, though they would have to use two realms, because of Gen1 and Gen2. One more thing that gets me thinking is the Island of Darkness. It split from the mainland when the First Spinjitzu Master stuck his sword into the ground, as seen in the story in episode 20 (The Stone Army). That could be a realm, since of its other-worldly look. The Endless Ocean. I can prove it is not a realm because it is on the map of Ninjago (seen in episode 21, The Day Ninjago Stood Still, when it zoomed out to get a bird's eye view). It is the thing that splits the mainland from the Island of Darkness. Possible Realms: The Digiverse, Bionicle: Gen1, Bionicle: Gen2, and the Island of Darkness. With this I conclude my reply. Thanks for reading. Sincerely, The16RealmsOfNinjago
