- It's unclear how outer space fits with the concepts of the realms and the Ethereal Divide that were introduced in Possession. According to Tommy Andreasen, outer space is not a realm; the realms are "just places", not planets; and the exact relationship between realms in terms universes or dimensions is "Whatever ensures creative freedom."
- It is possible that when Andreasen said space is not a realm, he meant it is not a realm separate from Ninjago. In this the case, it could be assumed that the universe itself is the realm most commonly known as "Ninjago" because that is the name of the continent on which most of its inhabitants live.
- The Hageman Brothers almost did a season about aliens after Rebooted, and the Project Arcturus storyline was going to be setting this up.
- According to Tommy Andreasen, Ninjago is unlikely to visit space in the future.
- When asked if aliens would appear in the series, Andreasen said, "Not on my watch."
- Outer space is not a realm.
