I'm just at the last etappe of Act 1 (just after the Party together with Tiefling-Refugees, ready to venture down to the Underdark), playing as an Tiefling-Warlock, it seems to me "naturally" to be most open to a closer Relationship to the other Tiefling in our "Band of tadpoled Adventurers"...
And now i have to read here and elswhere about, what the Game-narrative has planned for KArlach...its now difficult a lot to me to simply continue with the above mentioned Relationship to this certain Member and even develop it up to some Sort of Romance...
It really seems either poorly written narrative around KArlach because of different reasons (like short Time for Development or some other) or its following the "Trend" in narrative Games with strong relationship between Players and Avatars to "force" unhappy endings...
I'm not very happy about this kind of Storytelling in a "Baldur's-Gate"-Game, but imho there is less hope that Larian "just gets the corner" regarding KArlach's fate...
