I'm not speaking about quests for them, but if you get an actualization in your journal when you get there, saying that you can/may look for source evidences/signals there, and you find a pile of corpses behind a waterfall and your chars don't even have a single word to say about it, IMHO, looks that this place his unfinished.
If this place is working as intended, sorry, but IMO the devs would have put some type of signal that the place is only a completely dumb place in a fantastic game, where no other place until now was dumb.
