@mozhad I love the idea of making the goblin camp YOUR camp. You start the game camping in the woods. When youre with druids it is a little area next to it thats all druid-y. If you change allegiances it says "Taking this path will move your camp to the goblin fort and you will no longer be able to visit the grove as a friend. Continue?"
Or just have some of the goblin npc's tag along in your camp. Minthara could even replace Halsin or become a full companion by the end of the raid. Also one more thing, Larian told us they handed us the evil companions, yes some of them are evil but it seems like only one of them have any interest in exploring the power of the tadpole. It's why I think adding some drama with the information Minthara could provide would make things interesting and make some of them join Astarion's camp on controlling them. Chiefly as I said in my post, when it comes to evil stories in rpg games, well written ones you need a good incentive. There is none here at the moment. The good route in the EA is actually fairly developed in comparison.
