>Do I then need to discuss again and get a new location or can I return to that location more than once?

The wand goes to a new location. You need to discuss again for another hint. However, it's possible to find them without the hints if you look in the right place.


>If I need to discuss and get a new location each time will I eventually start getting repeats?

It is possible to get repeats.


>If too much time passes will the guildmaster give me a new hint to a different location?

Yes, but it's a long time.


>Is there another post that I missed when searching about this topic someone could point me to?

I don't know.
