When asked about his past, HOBBIN hails from Gullykin and is sick of the simple plain life he has there. When you meet him he asks the party if he can join them in their adventure. Ever since he was a child, he has was always fascinated by the stories he heard about his Uncle and his adventures. By nature the halflings of Gullykin are not adventurous but simple farmers who would rather stay home and enjoy their simple lives. Hobbin is young and eager and ready for adventure. He would like to visit the famous Durlag's Tower and would like to visit Baldur's Gate since that's where he last heard his Uncle was at.

She travels to Beregost to find someone who is seeking adventure like herself.
When asked about his past, THORIN says he's from the famous Stoneblade clan who were once Durlag's captian of the guard for many years.
