I guess it would not be hard to create a story that explain how Halsin recently become the new leader of the grove even if he's not a archdruid.
I'd also like him to become a non origin companion but obviously he can't be a lvl 4 or 5 archdruid, it does not make any sense.
The story and the world lack of coherence. It's not the first exemple we talked about and probably not the last.
Kill the actual archdruid and make him the replacement. He's a terrible leader, so it'd be a good way to explain that too.
