Okay, but why should I bother joining them when the first encounter I had was them trying to kill me? As far as I know they have nothing to offer me, nor do I have any reason to believe that showing up to their camp would be particularly fruitful. Especially when I have a reason to believe that they have captured the one guy who could actually help me.
I'm speaking from a game design point of view, not necessarily a lore perspective, the mention of half-drow was just to show I was trying to get into the headspace.
