(I tried piecing together the lore as best I could. Sorry for any mistakes!)
Born and raised in Len'miruel, Serelinde belonged to the respectable Laris'siol family. Her father served as a junior librarian under the Okarir'maehr, cataloguing submissions to the Eternal Library. Her mother worked as a silversmith who maintained the city. Serelinde was a naturally quick study from an early age. As a girl, she came to appreciate art, science, and order after watching her mother weave these concepts into Len'miruel. Her father also challenged her with concepts he'd learned sorting through books passing through the Eternal Library, as well as subjecting her to verbal sparring. This honed Serelinde's appreciation for knowledge into application and encouraged her curiosity.
Serelinde had blazed through the Eternal College's curriculum faster than expected by the age of thirteen. However, her exposure to concepts from around the continent led to a silent, nagging question. She agreed wholeheartedly with the maehr'sae hiulun'ehya. Progress was a fact of life. But health---Serelinde could not understand why the Mali'aheral defined it as racial purity. Her culture taught her to think with unerring logic and yet she found no justification for the creed's latter half.
Decades passed. Eventually, even Serelinde's taste for Elven science and art began to wane. She could only master so many theories and take the same tests so many times. Her thirst for knowledge hadn't waned though. She sought to quench it in a new field: magic. Maybe not so much doing it, but at least understanding it. Luckily, her father's position at the Eternal Library gave her proximity to restricted books the College had dismissed as primitive and dangerous. Subjects such as Druidism and Deity magic.
Serelinde snuck in and began reading. She was amazed at what she saw, and started to realize that perhaps she was not bored of Elven knowledge---but maybe Elven life itself. She had always been controlled and dogmatically taught to think along the narrow step-by-step path of apathetic logic. Was that not itself an impediment to progress?
By her fifty-seventh year, her father raised Serelinde's academic record to the Silver Council and recommended that she join him as a librarian under the Okarir'maehr. They agreed. Sere spent two years in the role---to learn what it entailed and, most of all, to make her father proud. She tried to want it. Tried to enjoy the functions she was expected to attend as someone being groomed for the position. At the same time, she gained nearly unfettered access to forbidden texts. She continued to learn.
By sixty, Serelinde realized that she would never force herself to want this life. Her passion lay in the books she'd seen---and most of all, the wonders of the world they alluded to. Places she hadn't seen. Peoples she'd never met. Topics she wanted to discuss with flesh and blood rather than parchment and ink. So she made the hardest choice she'd ever made, and one she wasn't sure was right. She penned a carefully worded letter to the Silver Council asking for leave to explore beyond the city. She was not rejecting the role; rather she needed more worldly experience to better serve as a librarian. And thus, Serelinde left the only home she had ever known.
Her travels showed Serelinde things she couldn't possibly imagine. All the while, her desire to learn magic grew as she realized that magic could not be understood without doing it. She missed home though. Not so much the control, but the familiarity and her parents always being there for her.
She was fifty seven when word of the Massacre of Haelun'or reached her. Suddenly Serelinde's world shattered. She had left, and now the home she loved was gone, and the life she knew would never return. Nightmares began to plague her that she had made the wrong choice.
Now she heads back to Len'miruel to see if her parents still live.
