Well after listening to a Entrepreneur book for the past copable of weeks, I came up with Quartz the goblin merchant. 

There was fire in the goblin worn. To young Quartz he didn't understand why they were screaming and running or why his mother put him in a wicker basket. "mommy! what is going on?"

"Quite!" She ran to the back of the worn where the tribe's stream was and put the basket into it.

"Mommmy!" that was the last time Quartz saw her as an adventurer struck her down. The stream carried Quartz to the surface river. Until lady Odilia fished the basket of the river. Odilia was compassionate woman who took the young Goblin in. At first it was like trying to tame a wild dog, confused and scared Quartz fought her tooth and nail especially around bath time. Odilia gave Quartz the best education she could. She taught him to play the lute, to read and the value of coin but above all the art of the haggle. Odilia loved market day of their small village to her it was the opportunity to meet with friends, what Quartz love most was the days when exotic goods merchants came into town. With their strange animals, pungent spices, metal works of all description and works of all kinds of arts. 

The most important of these merchants was the one that called him over and asked him. "Well my young Goblin friend, each time i make this run you are here with your questions and always try to sell me some of your glass works. But I have something speacel for you today." gesturing to the tarp covered cage. " This here is an example of a rare and exotic creature. That I was contracted by the great king Snow Beard of the dwarves to acquire for him. So, my young friend can you tell me where the creature came from." He pulled the tarp off.

Clapping his hands in delight at the joke Quartz said. "No, that's not an exotic creature! That's Miss lassies' old tom cat Buster." Chuckling the merchant released the angered feline. That night the merchant came to lady Odilia's house and offered for Quartz to become his ward and apprentice to the merchants guild. Troubled Odilia asked to sleep on it. Quartz couldn't sleep thinking how great his life would be as a merchant. So, he snuck onto the cottages roof to look at the stars. 

"Can't sleep?"

"yes maim"

"I thought about DeCards offer and I think it would be good for you. I taught you as much as I can here, its time for you to see more of the world just don't forget old Odilia." Hugging her Quartz swore on all the goblin gods, all of whom who didn't count Quartz as a fallower, that he will come and visit as much as possible. He visited her a copable dozen times as his travels took him back to the village. His last visit was after finishing his apprentice ship. That time the small town was razed to the ground by a band of bandits. Running to the nearest town he found the refugees of the town but no Odilia. Putting the refugees to the question they told him of the story of how bandits came into town a month ago boosting of plundering a tomb. A few days of down time had the bandits itching for some entertainment and decided to torment the villagers. What stroke fear in Quartz's heart was the description of the bandits symbol dredged up his worst nightmares of the worn the adventurer who slaughtered his people. After twenty years he had his first lead and connections to fallow that lead, but he also had the mystery of Odilia solve as well. Only time will tell if he finds the answers.

This is an amazing backstory. So, we have: goblin, not sure on class, and either charlatan or guild merchant/artisan. I think this is good, but have one more question: why would they join a group of people who could have KILLED their MOTHER? To get revenge? Or do they not care/remember?

the background would be guild merchant glass work but dreams of doing exotic goods, with class would be lore college bard. I was thinking that Quartz would probably join a party for the security and would argue tooth and nail to keep anyone from having a repeat of the worn.
