Ancestry/Background/Class: Unbreakable Goblin/Teamster/Bard
A notable event of your past: Grazmik saw a traveling troupe come through her people's lands and was fascinated by them. She stowed away with them, watching them perform from town to town for weeks before finally being found and expelled from the group. This was the beginning of her travels.
A short-term goal for your character (something that could be achieved by level 3): Earn the respect of a small group of people, enough that they see her as an entertainer/inspiration rather than just seeing her as a goblin.
A long-term goal for your character (something that would happen after or beyond the scope of one adventure) Gather enough knowledge to write a grand "history" of Golarian. Not the type with dry facts and numbers though. Something much greater and more interesting, that will truly entertain as well as . . . well it'll kind of educate at least. (Think Heroditus)
Why are you working for Bort's Caravan, or why are you traveling with him to Etran’s Folly: Grazmik needed to get out of her town more than anything. But she didn't have the money to do it on her own, so she began working in whatever way she could to earn her way through traveling. Bort's Caravan just happened to be going away from her last stop at the right time, and Bort was willing to hire her to take care of the horses (yes she is aware that most goblins hate horses-she just can't understand it).
