Here's the background for the last character I played, Fim the Halfling Rogue (Chaotic Neutral). It's lengthy:
Fimbul Ferryford - Sociopath with a Heart of Gold
Fimbul Ferryford is the firstborn of Fenwark and Beki Ferryford and arrived into the world just over 20 years ago. In accordance with Halfling tradition, being the firstborn child, he was given an alliterative first name like his father. The Ferryfords went on to have two other children, a daughter (Amabelle) and a son (Cugan). The family was poor and lived in a one-room hovel in the slums. But Fenwark was a Halfling of some talent for fixing things and found work with a Gnomish tinker named Redef. There he was able to make enough money to support his family if only barely.
Beki was also hard working and would wash linens for the slightly more well-to-do folks in the merchant quarter. Every morning of Fimbul's youth was spent hauling packloads of clean laundry to the merchant quarter and then coming back with the dirty. In the afternoons, he would help watch his brother and sister while his mother scrubbed the enormous bedclothes of the humans. In the evenings he would sometimes help his father repair some item or other that he brought home from work to be repaired. Fenwark had a particular knack for fixing things with small moving parts such as hinges and locks. Redef began to give most such objects to his assistant to repair and this became a relatively profitable arrangement because such items were expensive and people would pay a good deal to have them repaired rather than purchase new ones.
Eventually Fenwark and Beki's work paid off and they found that they had saved enough money for Fenwark to open his own locksmith shop. Redef was somewhat angered at Fenwark for leaving as this took some of his most profitable business away. He offered Fenwark a larger cut of the fees for his work but the hard working Halfling would not be swayed. He opened the doors of his new shop and his business rapidly began to grow. It seems that locks are in demand in the less affluent parts of town where folks have little and wish to protect it well.
Fenwark's business attracted something besides customers however and it wasn't long before the thugs showed up. A human tough named Hacmed (or "Hack" as he was known in the slums) and his Half-Orc sidekick, Oth, showed up at the shop and hinted that prosperity such as Fenwark was experiencing tended to attract jealousy. They offered to keep him safe from "the undesirables" for a small fee. Not wishing to risk the safety of his family or his burgeoning business, Fenwark paid them their money and they went away. But not for good.
As time went on, Fenwark continued to do good business. He tried to pass on his skills to his children. He found that Fimbul was good at manipulating the lock mechanisms, but had little patience for the work of repairing them. Cugan showed more promise as he seemed willing to play with the locks for hours on end. Amabelle showed less interest and stuck close by her mother's side, learning the lessons of keeping up the small apartment above the shop. That was fine by Fenwark as it seemed that the income generated by his shop would mean that his children could enjoy a bit of leisure time for a change. They'd never be rich, but comfort was within grasp if things kept up the way they were going.
Such hopes came crashing down when the thugs came calling again. Just a few days after Fimbul's 18th birthday, he heard a commotion from down in the shop. He went downstairs to find his father lying unconscious on the floor and the till from the store missing. The door was swinging on its hinges and Fimbul caught a glimpse of two large forms retreating down the street, one of them unmistakably a Half-Orc. Fimbul's first impulse was to chase after them but he ignored it and went to the aid of his father. Fenwark had obviously been severely beaten but he still lived, for the moment. Fimbul carried him upstairs and the rest of the family helped get him into bed. Fimbul could tell that his father was barely clinging to life and he left the shop and raced to the nearest temple to try and bring aid.
Fimbul quickly began to learn the hard life lessons that his parents had tried to shelter him from. The temples were only interested in helping if you had coin in hand or were someone of import. Fimbul's promises of payment seemed to fall on ears that were no doubt deafened by the dirty young Halfling bearing the message. Time and again he was turned away, sometimes not even allowed in to speak to a clergyman. He returned home a few hours later to hear the soft sound of his mother and siblings weeping upstairs. Fenwark was dead.
Fimbul's experience with the authorities was at least as frustrating and disappointing as that with the temples. They could scarcely be bothered to speak to him and certainly had no intentions of rooting through the slums to find the murderers of some Halfling commoner. One guardsman finally told him point blank, "As long as the murderous filth stays in the ghettos, they can kill whoever they want." With that callous statement, the last shred of Fimbul's innocence was torn away.
Had he acted quickly to sell the business and taken what money they'd saved to invest elsewhere, the Ferryfords might have been able to eke out a meager but sustainable existence. But Fimbul knew little of such things. He and his younger brother tried their level best to keep the business running in honor of their father. But Fimbul just didn't have the knack for the job and Cugan, scarcely more than a child, just didn't have enough training. Each week saw fewer customers and when it became obvious that the business had to be sold, there was little to sell. The Ferryfords closed the shop and moved back into a one-room hovel. Beki Ferryford went back to doing laundry but she was not as young as she once was. The walk to the merchant quarter took its toll on her and she began to rely more and more on her children.
Fimbul was a young man filled with a hot core of determination, cynicism and resolve. He silently vowed that his family would not live like this forever. If the mean streets of the slums felt like taking what his family had, well then he would just take it right back. Fimbul began to comprehend that, in a lawless world it was the strong who could take what they wanted and the strong who could keep what they took. But Fimbul was smart enough to know that he would never be strong the way that Hack and Oth were strong. He would have to find a way to be strong by being smart and quick.
Fimbul took to the streets and began to put his smarts and agility to use by begging, stealing and conning every copper he could find. He would nick an apple or two for his siblings to eat for breakfast. Before lunch he would beg a handful of coppers from the Merchant Quarter, often being paid off by the merchants themselves just to leave the customers alone. He worked the docks offering himself as a tour guide to foreign sailors, sometimes lightening their purses a bit when they got drunk. On his way home in the evenings, he might pick up a couple of silvers from a quayside dice game and buy some groceries for a couple of days.
One such dice game ended with an unexpected outcome. Fimbul wound up winning and being owed money by a dockhand named Woller. Woller came up short on his losings and Fimbul knew that it wasn't likely he could produce any more coin even if he tried to beat it out of the man (which it was unlikely he could do anyway - dockhands tend to be strong). Instead, Fimbul sensed an opportunity and let Woller owe him and, being as how he didn't have a copper to his name, he even bought the man a grog at one of the dockside bars. His generous treatment paid off and the following week Woller paid him the money and also cut him in on a minor heist. It turned out that Woller had a "lady friend" who tended bar near the docks. She had overheard a couple of men bragging about how they were drinking instead of keeping a close eye on some cargo the captain had left aboard the ship. A few hours later there were a score fewer bottles of Kingdom wine headed to Cualanto. Woller's gambling debt was paid for ten times over and Fimbul bought him another mug of grog.
One saving grace for the Ferryford family was that when their luck had truly ran out, Redef showed his true colors. He would drop by a loaf of bread or a basket of vegetables now and then and make sure that their clothes stayed mended. Fimbul tried to repay this kindness by occasionally doing odd-jobs around Redef's shop. Fimbul soon learned that, kind though he may be, Redef was not as law-abiding as he appeared. Shady figures frequently appeared in his shop looking to sell goods about which they preferred few questions be asked. Redef would buy such things at low rates and find buyers for them. If necessary, he would use his tinkering skills and the minor magics afforded to Gnomes to subtly alter the appearances of such goods so that their origins would remain secret.
It was on one such occasion when Fimbul was cleaning up around Redef's shop that he had an experience that would sever any links to the innocent Halfling he once was. He heard a commotion from the front of the shop and came out to find none other than Oth the Half-Orc bullying Redef over what the Gnome was willing to pay for a silvered belt buckle with a few semi-precious stones. Fimbul crouched low near one of the many small workbenches, not wishing to become the next target of the hulking Half-Orc's wrath. As Oth became more belligerant with Redef, Fimbul reached out and silently grabbed a long poiniard that lay waiting a repair to one of its quillions. When Oth backhanded Redef in angry frustration, Fimbul took three quick steps toward his flank and planted the blade in his kidney. Oth screamed in pain and dropped to all fours and that was when Fimbul shoved the thin dagger into his armpit and left it there. Oth died within moments.
Fimbul quickly drew Redef close in a conspiritorial embrace and whispered that they must conceal Oth's body lest his partner Hack find out what had happened. Fimbul told Redef to clean up the mess and to keep Oth's corpse in the back room until later that night. The Halfling then departed taking with him a short, sharp knife, normally used for cutting leather. He pooled the dozen or so silver coins that he had saved away for an emergency. He spent half on a good (by slum standards) bottle of liquor and the other half on a prostitute. Acting in the guise of a messenger boy, he told the whore that he was sent by Oth and wanted her to take the bottle and spend the evening with Hack and to tell him that Oth, "got a good price for the buckle". She did as she was told.
For a woman who rents out the space between her legs, time is valuable. So it was no surprise to Fimbul when she left Hack's apartment a few hours earlier than the silvers should have bought him. Fimbul slipped inside nearly silently but had he made a lot of noise, it wouldn't have mattered in the least. Hack was sprawled across his cheap, rope-bed, completely oblivious thanks to the bottle Fimbul had bought him. He didn't even stir when Fim slit his throat. If Fimbul carried any regrets away from the warehouse, it was only that Hack had spent his last few living hours in relative pleasure. What he did carry away was a box of coins stashed under Hack's bed. It held enough gold to feed his family for weeks and to outfit himself with something better to defend himself with than a leatherworker's knife.
Oth's body found it's way into the harbor thanks to a few coins and a pair of thirsty dockhands with whom Fimbul was acquainted through Woller (who took his usual grog as a commission). Unsurprisingly Oth and Hack had few friends and more than a few enemies. None of the inhabitants of the slums cared that one was missing and one was dead. Nor were they particularly hopeful about the fact that they were gone. Port Mangsa had many problems but a lack of thugs to fill a void was not one of them.
Redef would later comment that Fimbul had "snapped" but, although he never denied it, it just wasn't true. Fimbul had been waiting for the day when he would be able to kill those responsible for his father's death and this was the perfect opportunity. He did not do so out of any particular sense of revenge or justice. The fact was that if he was going to gain an upper hand in his small community he needed an opening in the power structure and that meant shaking things up a little bit. The fact that he was able to kill Oth in Redef's shop and thereby make the Gnome an unwilling accomplice to his double murder meant that they were now "blood brothers" after a fashion. In Redef's mind, Fimbul had saved him from possibly being killed at the hands of Oth and the sort of gratitude that generated could not be bought with coin. While Redef lived, Fimbul's family would not go hungry and Fimbul would be able to get an excellent price on any questionable goods he brought to the Gnome to fence.
Having secured a better daily lot for his family, Fim began to distance himself from them, starting with using a shortened version of his name. He also began to immerse himself more fully in the politics of the poor parts of Port Mangsa. He learned everything he could learn from new trades to which guardsmen slept with which whores. He bought himself the best used equipment he could find and had Redef help him make sure it was in serviceable condition. Woller put him in touch with a few sailors who could teach him some more refined knife fighting techniques and he practiced throwing his daggers and darts in every spare minute.
Ultimately he began to see that his best option for a profitable future was not going to be in the copper and silver world of the slums and he started to gradually move his interests to the more upscale areas of the city. His two most recent ambitions are to try and make inroads into one of the various smuggling operations run out of the docks district (he's hoping that Woller has some information about this) and the formation of a network of informants who may hold real power: The Practitioners Guild. Having recently started working at a place called Ichabod's in the employ of a Mistress Silvanna Wainwright, Fim's prospects hold a great deal of potential.
In the mean time, his mother no longer has to scrub and haul linens and Cugan has begun to apprentice under Redef as a tinker (with the understanding that Cugan is to know nothing about any illicit goods that Fim fences through Redef). Fim is hoping to possibly secure a position for Amabelle as a scribe at the Practitioners Guild for she shares the quick wits of her older brother. In a rare moment of optimism, Fim even dreams that she might become a Wizard someday.
