Questgivers don't give the slightest indication of where things/houses are.
But they do.
Take Hansel for instance, even reading his mind.
If I remember correctly, This is the guy standing near the captive undead, right?
If you listen, he says something about "being so scared, he left a trail of groceries all the way to where he is right now.
Then that ghost - CAta... something right at the start in the square, he meets you somewhere but where the heck that is is another mystery.
As for the ghost, Caracalla, his house is not accessible early game, but there's no rule in the world where you need to be able to solve your quest right away once you receive it, right?
And that's exactly what I liked about FoV, the quests are connected to each other, and if you let the game run it's course you see it all fall in to place, rather than the usual "Do this, okay thanks, we're done, here's your free exp, now get out of here."
