How do you get to the Slaver's Hideout?
If you or anyone who's reading this haven't figured it out yet, there are 3 ways to know the location. You can find and defeat, or probably convince, the caravan of slavers on the desert beyond the north entrance to get the directions to where it is, this is a random encounter btw, or go behind the salve house by following the wall to find a way in, from there you convince the rest of them to willingly bring you there or something. Keep in mind that they don't trust strangers or smth like that... and uh, save before both, you don't get second tries on those. However for the third one you have to work on the town's brothel and seduce a slaver I suppose(?), but unfortunately I do not know what to do beyond that point (sorry).
[Kind of a spoiler imo] Also you need to disguise yourself as one of them eventually, so probably try your best to spot some small details that could ruin the disguise too. Oh and pay attention to the color and position of "it", don't worry you'll understand what im talking about soon enough.
So, I hope I helped you out on your journey! Anyway, just search for the wiki if you're still struggling I guess, I did it for this part of the quest too lol.
