This is something I'm still a bit confused about, and it's holding me back from making certain edits to articles. In "Return to the Pride Lands", Kion relinquishes the title of Lion Guard leader to Vitani, and her group becomes the next Pride Lands' Lion Guard. Kion's, Beshte's, Fuli's, Bunga's, and Ono's Lion Guard marks all disappear, but are replaced by Tree of Life marks. So are they part of the Night Pride now? Or, since Kion gets to keep the Roar of the Elders, are they still technically a Lion Guard (but are now serving the Tree of Life)?
Personally, I'd like to believe that the former Lion Guard is now part of the Night Pride. But I'd like to hear some other opinions.
