Character Info Comments
Davis Dock of Carona The only useful purpose this guy seems to serve is that he tells you where you are when you land on Carona.
Klaus Owns an antique shop Klaus is a very instrumental character in the game.  Make sure you visit him every once in awhile throughout the game.
Mira Lives with Klaus Mira's not so much a useful character, but she's Klaus's wife and she likes to cook!
Elena Lives with Klaus Elena can be useful at times, but not very many times.  She's Klaus's daughter and she loves to talk!
Ms. Cartha Owns the Inn Ms. Cartha is a necessary character in the game because after you save Elena from danger, you get to stay in her inn for free!
Tonio Owns a shop You can buy defense and attack items from him.  It's a MUST that you check with him to see every now and then!
Hobbs Owns a shop Unfortunately, Hobb's items are a bit on the expensive side until you bring him the Rare Wine and then the prices drop to 5000.
Jargen & Annette Work at the tavern They don't really have a real purpose unless you want to buy drink (replenishes MP) and when you give them the Legendary items.
Leeson & Solin Own the hotel Unfortunately, you have to stay here once (500) in order to see a dream sequence. 
Father Doyle Priest in the Church Father Doyle is so nice in that you "donate" money and he gives you Life Coins in return!
Graham Old adventurer When you're stuck, talk to him.
Neil Collector of rare items If you find something rare, go speak to him.
Marcum Trader When you're stuck, talk to him.
Marco little boy He's one of the only little boys you find in the game (Prima Doll doesn't count because he's not real).

Make sure you talk to these characters at least once every time you return to town after an event.  A lot of them have something new and different to say.
