The daughter of Order of Society scholar and librarian of The Monastery of the Glorious Shield of The Nameless One Eilin Dubhglas and the eldest of Golden Knights member Eslo Lightfoot's great number of offspring, Rosemary (usually shortened to Rose) was conceived during his time as squire to Eddard McHayden. Rose was essentially born into the monastery and spent much of her childhood roaming the monastery's vast private library. Her mother, resenting the fact that Eslo vanished before finding out she was pregnant, never told Eslo about her, and so Rose never met her father until she sought him out herself as a young adult. Even so they only met a handful of times but they did form something of a relationship prior to Eslo's death in 3A 210, and she deeply regrets that we wasn't able to spend more time with him and that they couldn't be closer than they were. However, she and her mother are close, as she is with her stepfather and younger half-brother, though her stepfather, a Troll Bridge Association accountant, has found it rather frustrating that someone of her intelligence has decided to join the church rather than do something "more productive" with the knowledge she has.
Growing up surrounded by books and inheriting her mother's curious nature, Rose quickly became an avid bookworm, reading literally thousands upon thousands of them over the years. She quickly became particularly interested in learning about Tiran history and, more prominently, about the arcane and thaumatology in general after a visit from the head of the local Grand Order of Wizards tower to the monastery. Even now, she has a particular expertise in the arcane and the occult, and tends to try and record every spell she sees for the reference of future knowledge-seekers. This has not been without hardships though - one of her earliest attempts of casting a spell of any real size backfired, creating a massive Weave‐scar that covers her entire right arm and much of the right side of her upper torso and neck and coming close to burning down part of the family home. Said scar brightly glows an almost neon blue whenever she uses a spell that requires large amounts of magical energy.
This childhood of self-isolation also had some serious downsides, as her lack of friends her own age in her youth besides her brother caused her to be extremely socially awkward and this, combined with her scar and her height (being part-Halfling, she is considerably shorter than most other Wood Elves), led to no small amount of mockery and a massive hit to young Rose's self-confidence. This has resulted in an individual who is highly intelligent and knowledgeable, but is also extremely shy and socially anxious in stark contrast to her father's famously outgoing nature. She also has next to no combat experience outside of sparring; though the large and eclectic collection of spells she knows can compensate somewhat for this if necessary and she does have some in-house combat training as required by all monastery staff for safety reasons, all of her knowledge in the area of actual battle is entirely theoretical prior to her entrance into the story.
She formally joined the Order of Society as an apprentice librarian under her mother after completing her national service, where she worked in the archives of the Troll Bridge Association's Balla branch. Rose was quickly noticed for her extremely potent weave affinity, and was frequently enlisted to help with magic and rituals which required a large number of people, including leading one of the thirteen traditional ritual circles during the coronation of the incumbent Pope of the Church. It was also around this time that she purchased the magical hammer known as Duskcrusher, accidentally mistaking it as a harmless feather duster in a thrift shop and only discovering what it really was by accident.
Rose eventually surpassed her mother in rank and succeeded the chief sacrist of the monastery upon their retirement, much to the pride of her mother and stepfather. Her place in the shortlist of successors, unbeknownst to her, had actually been bought by her stepfather via the donation of an extremely rare and valuable book of ancient arcana which ironically Rose herself has used extensively during her studies. Despite this, she has proven to be very well-suited to the role, and she takes her job of tending the library and the reliquary very seriously despite her being bad at standing up to others, though she still spends much of her downtime hidden somewhere in the library with her head in a book, or indulging in her other, slightly more unusual hobby - making crochet dolls of local wildlife. She lives in a small cottage just outside the monastery grounds.
When the Balla Incursion began, Rose began assisting in the monastery infirmary to help injured civilians who came in for protection. She also began moving the more potent magical texts from the monastery library to a secure location to avoid them falling into the wrong hands should the city fall. However, much to her chagrin she was forbidden by the father superior to do the same with the contents of the reliquary. Following this, she was asked by Xvim Wrenlow to assist the Grand Order of Wizards in operating a teleportation circle to facilitate the evacuation of most of the city's civilian population, which has thankfully kept her out of the fighting until this point. After Nox's forces attacked the Grey Tower however, Rose bravely chose to step away from the circle despite her own fear and misgivings to aid in defending it alongside Qau the Mighty and Glaw Trwm, successfully fending off the contingent of skeleton soldiers that broke into the building. Following this the two inducted her into the newest incarnation of Qau's party, though not necessarily with her consent. Over time however, she has grown to embrace the company of her new allies, especially that of Qau with his genuine attempts to comfort her following the deaths of her family during the Fall of Balla. She and her new teammates bonded particularly after clearing out a fort full of undead where activating a relic caused Rose a case of weave intoxication, during which Qau and Glaw tried to help her as she got over it and she opened up about her past, the loss of her parents and her own insecurities of being in her father's shadow (with the two finally realising that Eslo was her father at this point).
