you're all wrong. halsin's backstory actually has more to do with how the shadorealm formed than with the grove. the grove was what he did after he couldn't figure out how to deal with Ketheric, since he was now immortal. It makes perfect sense being the wandering druid he was before, that he would want to return to that life, and not be stuck at the grove. That's why he immediately jumped at finding a replacement for himself at the first opportunity.
you all are imposing a narrative on halsin that is most certainly not his own.
Im gonna agree with this. I never questioned him leaving the grove outside of the questions Tav has for him, which are natural to ask and wpuld be ones Id ask anyway.
He sees the first oppourtunity to really save his homeland in about 100 years, he jumps on it, not knowing how long he will be gone, if he will even survive to come back, knowing the flaws in the other druids and not wanting the circle to posisbly collapse in his absense, he asks for a replacement.
Gee its almost as if Halsin is responsible, mature, wise, and dedicated to things he cares about. I wonder whats up with that.
