Ren's fate was woven long before her birth, with the onset of Lucinda's story. Lucinda was a talented portal weaver and devout follower of the Eivyalhan goddess, Taladi. Eivyal was a dying realm, and as the seams of the universe came undone in that distant world, Taladi, the creator goddess, was able to catch a glimpse of another, younger universe that could be consumed to save her own: Arvastaira. After several unsuccessful attempts with other champions to cross the rift between universes, Taladi managed to guide Lucinda to Arvastaira, setting her plan to consume their world in motion.
Instead of biding her time in isolation as Taladi had wished, however, Lucinda chose to venture out into this new world and discover what it had to offer. As a result, her unusual presence was noticed before Taladi could transfer a greater extent of her powers and will to Lucinda. Her champion's presence was detected by Atei himself, the creator god of Arvastaira. Ever the curious, experiment-minded soul, Atei took it upon himself to study Lucinda and her odd powers, which eventually resulted in the creation of a child with lineage from both universes. The child had two purposes: to serve as a curiosity, an unknown variable that would wander the world and provide Atei with data; and should it ever come to be necessary, the child would be absorbed by Atei as a reserve of power. This 'child', however, ended up becoming a set of twins due to the discreet influence Taladi exerted on the process.
As the secondborn, unintentional child of Atei's fenvasi offspring, Ren received little in the area of magical potential, positioning her to be promptly disposed of. However, after Lucinda pleaded with the creator god, Ren was instead cast out into the world under the assumption that she would either die in the wilds or live out an uneventful life among the fenva. Since the keirsi concentrated within her was so unremarkable, she was identical to a fenva in every way; she would have no trouble passing as one.
She was later discovered in a patch of Veseroluun woods and adopted by Ira Tarasa, an aging alchemist that lived on the fringes of society. Due to Ira's status as a neveniati, those who interacted with her were equally shunned and feared. But despite the loneliness that lingered in their lives, she still loved Ren like the daughter she never had, and the two lived together happily.
A few days after Ren turned sixteen, however, she would wake up in the middle of the night to find her home ablaze. When she found Ira in her chambers, her adoptive mother was dead at the feet of a masked stranger with wild red hair. The stranger, unbeknownst to her, was her twin brother Halvatt Sali. He proceeded to kidnap Ren and imprison her in a dilapidated vesera ruins, leaving her confused and terrified. A few days later, Ren overheard a conversation between the masked stranger and an unfamiliar voice debating the process they would use to extract Ren's remaining powers once they cut open her body. Terrified of what was to come, some form of latent magic within Ren began to stir, causing her to shapeshift for the first time in her life. Now in the form of a dragon, she broke through the imprisonment magic and fled the scene in a panic, knowing nothing but the need to get as far away from these people as possible.
After hours of adrenaline and erratic attempts to stay in the air, Ren managed to land in a secluded forest grove, where she would forcibly shift back into her regular form out of exhaustion. Though she was still afraid, the keirsi reserves within her had been depleted, and she struggled to go much further. Using the last of her strength to cry out for help, she caught the attention of a passerby fenvasi, Aidan Fasiran. Though he seemed rather shaken by this meeting, he offered to take Ren back with him to Resovinasis, the plane of the divine, suggesting it as a means for her to find the answers she sought. With nowhere else to go, Ren accepted, hopeful that this new path in life would eventually lead her to the truth of what happened that horrible night.
The gods of Resovinasis were taken aback by Ren's ability to achieve a draconic form, a trait only seen in offspring of the eldest divinities. However, try as they might, they could not accurately determine her heritage. The composition of her essence was entirely bland, with the only exception being her strangely poor control of keirsi that fell below the standards of even fenva at her age. Yet after much deliberation, they allowed the Elder god Yilensat to adopt her, not wanting this oddity of nature to potentially wander into the wrong hands. With her fate as a fenvasi set in stone, Ren was eager to find her place in the world, determined to follow her heart to whatever distant futures awaited ahead.
