That Helions and Lost are just different fur colors depending on their group having a female Hrothgar in it or not.
It just seems really weird to me and I kinda want some explanation about how it really works, like do Helions go grey from grief when their leader dies or what?
If a Queen is so important to them, why do Lost not join groups that still have a Queen and therefore avoid becoming Lost?
It's easier to just headcanon it as Hrothgar that live in more traditional society (Helions) and Hrothgar that are basically loners by choice (Lost), with that it wouldn't be an external factor that changes them but their own choices.
