This is Farah, half-elven female bard based on Dungeons and Dragons.
Farah is the daughter of two adventurers, her father a human warrior and her mother an elven archer/mage. Both parents eventually retired from adventuring when they earned titled of nobility and territory to look after. They married, and eventually had five children.
Farah was the third born, and she was quite an handful as a child due to loving to make pranks and being playfully misbehaved. A bit of a tomboy, Farah also tried hard to follow her older brother (whom liked forestry/hunting) everywhere he went. She was adorable, but also a lot of trouble.
Farah then gained two younger twin brothers, and since both her older sister and brother had left home to study/train elsewhere, she was now the 'older' sister. That was a turning point in her life where Farah became a lot more responsible and dependable.
Since Farah wasn't the oldest, she was never expected to be married off to another noble family, or to succeed her parents. Thanks to that, she enjoyed a lot more freedom about what she wanted to do in the future. She inherited her mother's talent for magic, and was a quick study when her father was teaching her older brother swordplay. Combined with a talent for singing, song-composing and a love of history - she eventually became a bard and left home to become an adventurer like her parents were before.
Being a nobleman's daughter, Farah grew into a well-mannered adult generally at ease in her own skin, with a genuine love for her people, which contributed to making her charming and outspokenly charismatic.
She's not quite the frivolous noble-lady, though, mostly thanks to her parents more humble origins and the sense of responsibility she developed raising her younger brothers. Her cheerfulness as a child grew into a more mature positivism.
Being positive lends her probably one of her best qualities as an adventurer: she's very courageous. She's not fearless: Farah does get scared, but rather than panicking or feeling sorry for herself, she tends to tenaciously look for solutions even if in grim circumstances.
