Mr. Biggs was relatively young, about 10-11(So, not quite an adult). When he quite literally exploded into a leading position in his small tribe. He would "lead" them for another year or so, mostly telling them to go get things for his alchemy. To his frustration, this often lead to them bringing back the wrong ingredients. Which he would "mix" anyway. Eventually, he made a "gun" from scrap metal and junk. At first, it was more of a chute that could propel his bombs. But, as he used them on random objects he got to thinking and made something that shot actual metal bits!
He had never been a particularly spiteful gobo, preferring to be left alone to mix his mixes and make and use his bombs and gadgets. So, he never led any raids or even told his very small clan to do so. However, this didn't stop certain goblins from attempting to attack a caravan. One, that was guarded by a priestess of Sarenrea and a paladin of Iomeade who were traveling with the Trade caravan. When the goblins fled, they followed them back to the small place Mr. Biggs and his small clan had made their home.
without the details, most of the clan was killed, but Mr. Biggs and his higher than your average gobo intelligence managed to convince the Priestess not to kill him and the remaining goblins if they promised to come with them.
Over the next few years, The priestess taught both Mr. Biggs and the other goblins about Sarenrea and how to properly behave in human settlements. Mr. Biggs picked up on things quickly, his higher than normal intelligence for a goblin and his love of fire helping.
Fast Forward another year, and Mr. Biggs was allowed to "live" among humans on his own, with of course, regular check-ups by the priestess. He has both a writ from her, and a large Icon of Sarenrea he must wear on his person at all times. For his protection. The priestess chose Sandpoint specifically because of its long history with Goblins. It took a few favors on her part, but the majority agreed, tentatively, to letting Mr. Biggs live in a ramshackle hut on the outer edge of the town.
Mr. Biggs over the past year has earned a reputation of an excitable, mild fire hazard. He often provides Fireworks for the town, and, under close supervision of the Priestess of Sarenrea provided a fairly decent firework show last celebration. And several, several more throughout the year. The town's opinion on him ranges from genuine curiosity bordering of friendliness to down right open hatred and racism. However, he has not broken any laws, save perhaps fire safety laws recently put to records, and pays for anything he gets with money that either he earns by selling random things he finds, his "poppers" as he calls fireworks, and a small stipend from the Priestess. So, the town puts up with his, almost endearing, almost dangerous, antics. Many of the more open-minded people in town have come to almost relish Mr. Biggs showing up, as it means that surely antics and/or hilarious hi-jinks are soon to follow.
Additional notes-
As for where it is going to go- I was thinking of Having him form an actual connection to Sarenrea, becoming a cleric, or possibly oracle if I can find a way to run them off wisdom. Like, not quite a chosen one, but a "hey look, goblins CAN be redeemed" aspect.
As for the character, he would, of course, act as a bit of comic relief hopefully. That is not to say he would be only humour, I have a couple of good ideas for ways to make him a serious character as well. But, being a goblin, humour will be in much of what he does. If only because the idea of a goblin knowing the exact amount of herbs to use in a specific recipe, their location, and their appearance can be a bit funny.
