Seed: Sionedwyn was once a great tree, and a beloved member of the Oakengrove community, same as most of her previous incarnations. Like the other Dryads, her 'birthplace' was a certain spot in the forest that she'd return to towards the end of her life, before eventually dying and being reborn. The initial hundred years or so of her life were spent growing as a tree in this spot, same as she'd done countless times before, finally emerging from her trunk in the form of a beautiful woman. There she began the ritualistic journey from the fringes of the Senshenk Woods to the fey court at its center, the 'capital city' of sorts of the forest's fey inhabitants.
Sprout: Though physically equivalent to a young adult by human standards, Sionedwyn had much to learn (or re-learn) about the world. She had some vague memories and instincts still intact from her previous lives, such as an innate connection to her birthplace and an intuitive grasp of how to reach the Oakengrove. However, she did not know how to fight, make clothing, cast spells, or even speak more than some basic words and her name. Some of this she'd learn in her relatively-brief pilgrimage to the forest center, but most would not come until she had rejoined her sisters and the other fey.
Seedling: It took a few months of slowly wandering, learning, and avoiding travelers to finally manage to reach the Oakengrove, crossing into the fey realm to the great delight of some of her old friends, and many new ones. There she was welcomed with open arms, a sister returned to the fold to the other dryads, a potentially friend and lover to many of the satyrs, and a source of pranks for many of the sprites and fairies. The reunion began as all do for the dryads, with the other dryads helping to teach her all she'd forgotten in her dormant state, and bringing her up-to-date on the goings-on of the past few hundred years. Queen Íde oversaw this directly, having been an old friend of her past incarnation.
It took little time for Sionedwyn to re-learn the basics, such as history and vocabulary. She had always been a quick learner, and each incarnation seemed to be better at it than the one before. What took much longer was mastering the manipulation of the forest's natural green energies. All the fey were masters in such manipulation, it being a key part of what made the Senshenk Woods - and all forests hosting fey courts - such a mystical and mysterious place. As a gift she was given a tome of fey lore, one she herself had been keeping through each of her incarnations, though with some extra incantations and songs added towards the end in her absence.
Sapling: She was taught alone for the first year or so, when another of her sisters arrived from the forest beyond and began to train in the magical arts as well. This newcomer was called Cerys, and was a rarity among the dryads - a first generation incarnation. As such, this new arrival had no past memories to rely on or experiences to build upon, a true youth surrounded by the near-ageless. Sionedwyn took Cerys under her wing, helping her practice the simpler spells and incantations that came more naturally to her than her new colleague, and eventually helping to train her more directly as she began to master the magic in her own right.
Sionedwyn completed her training much earlier than Cerys, and the dynamic shifted between that of peers to that of a mentor and her mentee. Now confident in her knowledge and abilities, she began to venture back out into the forest on her own, often returning back to the Oakengrove with interesting tales to share with Cerys, or unique items found in her travels. The two would bond over such tales, and Sionedwyn's added wisdom, and over time became close friends.
The Brambles: On one of her ventures out into the forest proper, Sionedwyn stumbled upon an odd section of forest she'd never seen before. Deep into the northwestern portion of the forest she came upon a section of dense vines and thorns, a stark contrast to the usual trees and light underbrush of most of the woodlands. Eager to explore this fascinating growth, she wasted no time in venturing deeper into the vine-filled area.
Traversing the Brambles was no easy task, but eventually Sionedwyn came across an interesting sight. In the middle of a thick tangle of thorny vines she saw a pile of stones in a diamond configuration, the center of which seemed to emanate with a strange energy she'd never felt before. She'd heard the others mention the forest having pockets of black energy, and as soon as she felt it she knew that must be the source. She was both excited and worried about the discovery, and though her curiosity made her want to stick around, her instincts told her to flee.
The Stranger: Escaping the Brambles proved more difficult than entering. She could not tell if it was her mind playing tricks on her, but to Sionedwyn it seemed that the thorns had grown denser and thicker since she'd entered, leaving little room to walk through. Her magic did little to aid in the retreat, the vines seeming to be only marginally affect by her spells.
As she tripped over one of the many vines snaking across the ground, the young dryad was shocked and a bit frightened to find herself being aided to her feet by a stranger. When she looked to thank the stranger she found herself face to face with something else she'd never seen before, not in this or any previous incarnation - a dryad with horns. Or at least what she thought was a dryad. The woman had similar features to those of dryads, though her skin was dark and the aforementioned horns. She maintained her grip on Sionedwyn's hand far longer than she felt comfortable with, and looked into the young woman's eyes with no expression as she did so. The dryad felt compelled to maintain eye contact, but after a moment her fear about the whole situation got the better of her and she pulled away, running off into the distance.
Corruption: Sionedwyn returned from her trip to the Brambles still a bit shaken, but excited to regale her friend with the tale. However, her relief at finding her way home would be short-lived. When she met up with Cerys to tell of her adventure, the younger dryad was pre-occupied with Sionedwyn's forehead. When asked, the girl explained that there were small protrusions coming from her head that had not been there before. The elder dryad thought little of it and continued her tale as usual, but worry began to seep into her mind about what the protrusions might be, and if they were the result of the strange energies she'd encountered.
Over the coming weeks and months more of her sisters began to notice the protrusions, and from their comments they seemed to be growing. Some of the pixies suggested she was becoming a man, as horns were only found on the entirely-male satyrs in the forest, as well as male deer. Others worried the effects had a more sinister origin. The satyrs, who'd spent the most time among the other races, knew of the tieflings and their connection to the demon lords. They suggested the horns were signs of Sionedwyn becoming corrupted in the same manner, the small protrustions the first physical signs of her transformation.
As more time passed it became more and more apparent that the satyr's assumptions were the most likely. Over the span of more than a year, Sionedwyn's horns grew out, more quickly at first before slowing over time, until they had reached roughly 1/3 of the size of an average adult satyr's horns. While many of the pixies still practiced their light-hearted teasing of the woman, most of the dryads and satyrs had grown increasingly distressed, some completely refusing to interact with her lest the corruption spread. She remained close with Cerys, who'd managed to finish her training and could join her on her adventures, but most of her closest acquaintances had now become distant.
Cinder: Growing more self-conscious the worse the corruption got, Sionedwyn opted to spend more and more of her time traversing the forest than among her sisters in the Oakengrove. Though not as keen on travel, she was often joined by Cerys for these outings. On one such occasion the pair stumbled upon another patch of the Brambles, this one different than the one she'd been to before. The sight left Sionedwyn fearful and anxious, as her last run-in had done little to improve her life. Cerys was more eager to explore it, convinced that the woman her friend had met was the source of her corruption, not the land itself.
She was eventually convinced by her friend to go in, and the sights were much the same as before. Likewise, as before, they found a pile of stones in a diamond configuration, and could feel the dark energy being emitted. At this point Cerys finally became fearful, and the two began to flee, Cerys leading the way as Sionedwyn followed. From behind she could notice things she hadn't noticed before, such as the vines seeming to slowly - barely noticeably - shift and writhe as the pair moved. Like with herself, Cerys was tripped by one of these moving vines, and shortly after emerged the strange woman Sionedwyn had seen before.
Sionedwyn did not know if Cerys' theory about the corruption was true or not, but in that moment she knew that if she could prevent it she would. As the woman approached her friend, Sionedwyn raised her hands to caste one of the many spells she'd learned from the other dryads to channel the green energies of the forest. However, it was not green energy that responded but black, and what she expected to be a viney rope to pull her friend away turned out to be a firey blast that left the younger dryad on fire and screaming out in pain. The other woman, seeming unaffected by the flames, simply turned and left.
Sionedwyn was torn between giving chase and aiding her friend, but ultimately decided on the latter. She grabbed her friend and pulled her out of the vines, and as soon as she'd left the Brambles she cast another spell, this one working as intended, to soothe Cerys' pain with healing water. The young dryad was unconscious from the pain, but still alive, and Sionedwyn carried her back to the Oakengrove.
Once back, the others initially lauded the woman for her bravery in aiding her friend to safety. When Cerys awoke, however, their opinions quickly changed. The young woman no longer looked up to the older dryad with respect and admiration, but fear and hatred. She'd shout at her to leave, and curse her name, calling her 'Cinder' for the burns and scars she suffered. The opinion spread as quickly as the tale, with the other dryads calling her 'Cinder' and refusing to interact.
Exile: As word reached more of the denizens of the Oakengrove, the forest's rulers were forced to intervene. After a short trial where they heard from both Cerys and Sionedwyn, King Mochán issued his verdict. The elder dryad was to be banished from the Oakengrove and stripped of her name. Despite protests and pleas to the queen for mercy - even bringing up their old friendship - the sentence was committed. The king brought her before the gathered fey and cast an ancient and powerful ritual, stripping the dryad of her connection to the Oakengrove and rendering her incapable of speaking her true name.
As the king spoke the final words of the ritual, the woman - now nameless - found herself alone in the forest, no longer in a court of her peers. She still felt a connection to the green energies of the forest itself, but her intuitive connection to her home had been severed - she could not sense its presence. She wandered aimlessly in search of it or her friends for weeks, months, possibly years, she lost track of time, but to no avail. Eventually she encountered outsiders traveling the forest and, having nowhere else to turn, decided to travel with them.
When asked her name, she tried to speak it, but she was unable to produce the sounds. No matter how hard or often she tried, she was now incapable of speaking or mouthing 'Sionedwyn'. Eventually, frustrated, she settled on introducing herself by the only other name she'd ever known - Cinder. Though it killed her a little inside to adopt a name that had been spewed so hatefully toward her by so many she'd once considered friends, she had no idea what else to go by. As she traveled and used it more the sting of its origin eventually wore away, and she became known officially - both to herself and others - as Cinder.
Hope: Cinder met many people in her travels, some kind to her and some less so. The few fey she met outside the forest, despite having no direct knowledge of her banishment, had an innate sense that there was something off about her and often avoided speaking with her. The few she did speak with seemed put off, and she eventually gave up trying to seek the aid of other fey all together.
In the time she wandered, sometimes alone, sometimes with small groups, she heard tales on occasion of a man with a similar goal to her own. He - a tiefling named Damocles - sought to purify himself of the demon taint that infected him since birth, becoming a human with no ties to Balfour or any of the other demon lords. Cinder figured that if anyone could understand her struggles and potentially aid her in her own quest, it would be this man.
It took quite some time from the first time she heard of Damocles to when she finally managed to track him down, but eventually she did find the man. Though he was initially wary of the woman, the two quickly became friends, bonding over their shared persecution and desires to rid themselves of demonic taint. She began to travel with him, aiding him in his aiding of others and the two jointly searching for clues that could cure their curses. Their group eventually grew as others joined for reasons of their own, until one day they stumbled upon a tower...
