Vhaldez, this might be slightly interesting in terms of your Kagha is bad topic - I left out quite a few Druid responses so as not to bloat the video and to not totally destroy any sense of intrigue for people. There's an option you can take to call out one of the Druids in the cave for doing nothing to help and being snarky about it and his response is basically "only god can judge me."
You know, I was worried about this kind of dialogue specifically. Even when you are a druid, maybe even especially because of it, these crazy xenophobes balk at you about their mission from the tree god to kick out the demonspawn. 🙄
Am I just not up to speed with FR druid lore? Is this supposed to be the correct characterisation of them as a class? Why does Halsin exist then?
I know Silvanus is all about "wild nature" in his portfolio which covers quite a bit more than just plants and it's also why he as a god is quite a bit stronger than most. It includes wild magic that occurs naturally, for example, which is why Haslin is all over the place. Devils are naturally lawful most of the time but more importantly those tieflings in the grove do try to take everything with no concern for nature. They are a thieves guild in disguise. Their main goal was to steal the idol and fence it as well as spy. They are not good in the slightest. They have been gathering info and stealing anything valuable on the way to the city. They stay in baldurs gate because they are already in someones pocket. Think about it. Cazador is after vamp boy, nightsong activity, hag deals, Minratha betraying lloth, the absolute activity and secrets, etc. All can be sold including us being tadpole hosts. The idol business was just a bread crumb to lead you to hints about what they really represent.
Edit: looking back a little, Kahga was very right to be hostile towards them. If you as a player let her go to trial, assuming you talked sense into her, she will be on trial for betraying the grove to shadow druids and nothing else most likely. I don't even think she wanted to attack the kid. You can see it even hurt her if you fail the save lol. Anyway I don't think people realized that was not even the only attempt to steal the idol either. You even have the option to do it yourself if you talk to a specific ncp tiefling.
