first, Im already on chapter four and have not explored any of the sites on the map except de'arnise hold and spellhold--how do i get to them?

second, me and the boys were in the copper corrnet and met a gut who wanted us to check out his lands around windspear hills, the icon appeared, but cant access it.

third, should i be busting in to every house in every district to find quests or wait till im told to go to that home or business.

finally, and this is for chpt 4 only, under spell hold i placed the items in each statue dais, correctly im sure, yet nothing happened. also i canyt find the 3rd stone to access the portal. one more thing, how many mithril tolkens are there I have 19.
