Since it sounds like Redgorge is the most likely place for Goran to come from, I will go with it for my home location before heading to Cauldron. Will you still be handling the roll for the traits?
Also since Goran is going to be older, at least as far as human standards go, if you could recommend a tavern that he worked before, as well as frequently visits after, becoming a cleric, that might allow some of the others to have met him prior to the adventure taking place.
Edit: Also the feat(s) that I had in mind were the Earth Sense and Earth Adept feats. I would take the Earth Sense one first, replacing Combat Casting if approved and tie it into his backstory as another reason his family is disappointed in his current lifestyle choice as they see him as being given a gift by the Dwarven gods, yet he still choices to embrace Kord and his doctrines. If you would prefer to work it into the plot, I could see the miners that remain at Redgorge being good teachers, as it would be something they would be able to use when searching for people in cave-ins/tunnel collapses.

[sblock=Earth Sense [General]
You are in tune with the earth beneath you.
Prerequisites: Con 13, Wis 13.
Benefit: As long as you are touching the ground, you can take a move action to sense the number of creatures within 20 feet that are also touching the ground and the direction to each one. You cannot pinpoint the location of any creature with this feat.
