Here is my significantly enhanced D&D-style (or rather LD&D) take on Baldur Gate III NPC and their background (and you may further enhance it if you wish):
Frogo’s Tale
Gender: Male
Race: Half-Halfling
Class: Screwed-Up Bard
While visiting Trademeet at the time of its famous Hog Wash Fair, Frieda, a comely Halfling maiden, attended the Town Hall Masquerade where she, as she claimed afterwards, met her true love. After all the festivities were done, she was on her way home to pack and say good-bye to the relatives and friends: it was decided that the couple should meet in a fortnight on the road to Waylaid Abbey for their marriage ceremony. Unfortunately, Frieda, who was not a particularly good rider, fell from her prancing pony and, according to the local witch doctor, sustained a head injury resulted in amnesia: she completely forgot that she was engaged to be married.
Few months later (which coincided with the revelation that she was expecting a baby) Frieda suddenly recalled the Masquerade affair but alas, she couldn’t recollect who exactly she’d had the affair with. Her memories were vague and elusive. Sometimes Frieda would swear that her true love was a moon elf; occasionally, when she was tipsy, she fancied a hairy Dwarven brawler. And when she was especially displeased with her dear Frogo’s torn pants and broken toys, Frieda insisted it was a wretched kobold she had a misfortune to dance with. Only one thing remained unchanged over time: her true love was not a Halfling.
Perhaps Frogo had indeed some foreign blood coursing through his veins: he would spend endless hours in the moon-lit forest, playing a cheerless tune or composing bad poetry.
His discordant songs had an odd effect on those who was passing through the forest unaware of the Half-Halfling’s dubious craft: fauna dwindled, two peddlers committed suicide, three fortune-tellers went mad, and five brigands scrambled out of the woods sobbing uncontrollably and begging the local sheriff to arrest them for Ilmater sake so they could pay their debt to society.
Finally, after two of Mayor Doggett’s daughters eloped with gypsies, the scandalized townsfolk petitioned the druids of the Witch Hazel Grove to rid their fair town of the notorious bard once and for all.
The druids delegated one of their moldiest members blessed with almost complete deafness and blindness and consequently impervious to the hazardous delights of the fine arts, to deal with Frogo. Elderly Hazelnut appeared before stunned Half-Halfling amidst flashing lightning and swirling clouds of choking dust.
What arguments the wise negotiator employed remained a mystery but after that interview Frogo promptly packed his mandolin and disappeared, and so did the druid.
As luck would have it, you will bump into this remarkable pair during your travels in Baldur Gate III.
Trudy’s Tale
Gender: Female
Race: Turnip-touched
Class: Alchemist
The respectable Jansen family was in the turnip business for several hundred years. The complex art of growing turnips in the cellar was perfected by the generations of Jansens tirelessly laboring in the cool depth of their vast basements.
Rory Jansen was an accomplished turnip grower whose flourishing cellar was the pride and joy as well as the envy of the whole Jansen clan.
Turnips were the sole object of Rory's affection. He talked to them and caressed the large green stalks while working on the patch and fertilizing the white bulbous roots with very special liquid compost. The secret Turnip Fertilizer Recipe was a legacy passed from father to son after the latter proved himself worthy of the honor.
One evening Rory was suddenly distracted by an insolent cat slipped in the cellar in pursuit of a no less insolent mouse; he stumbled and accidentally spilled the whole pint of his prized fertilizer on one of the most promising turnips. After banishing the cat and performing a careful inspection of the affected turnip, distraught Rory retired to his bedroom upstairs lamenting his bad luck.
In the middle of the night he was awoken by a strange noise coming out of the cellar. Rory lit the lantern and rushed downstairs. What he beheld in the cellar nearly made his knees buckle: a very little girl with long green hair was frolicking in the middle of the turnip patch.
Trudy Jansen proved to be a very smart girl and Rory was proud of his adopted daughter. However, it saddened him that his little Trudy exhibited neither desire nor inclination to pursue the respectable turnip-grower career. Instead, she was spending her time helping a neighbor, the old grumpy potion-maker, gather herbs, squeeze newt juice and brew smelly concoctions.
Soon Trudy was able to open her own shop she named “TJ Max”, and her budget health elixirs and discounted love potions quickly became very popular among gnomish and human customers alike. Any decent gnome would’ve been content to have such a profitable establishment but Trudy possessed the daring spirit of a True Turnip: she craved adventures more than anything else.
She sold her shop filled floor-to-ceiling with gleaming bottles of “Toe-curling Mana”, phials of “Effortless Vigor” and flasks of “Love Made Spiffy”, packed a small cauldron and left her hometown.
Trudy will join your party after you rescued her from the clutches of the dreadful Alchemist Anonymous Sect.
Benefit: Trudy makes free potions, 6-pack a day. Drink responsibly.
