Emperor Aneirin 'Cyne' of Aletheia

Emperor Aneirin Cynos Elyan of Aletheia (a.k.a. Cyne)

The sarcastic, uncaring and excessively stealthy noble son of Lord Andron and Lady Ceridwen, Cyne makes a name for himself as the recently-ascended ruler of the Aletheian Empire and, secretly, as both one of the higher members in the Eagle's Shadows and the Champion of Asmodeus. He was incredibly protective of his sister, Alysia Undria, until her mortal sacrifice. It was for her that he became Emperor, despite nursing a hatred for politics and a longing for freedom. He still carries a great amount of guilt over her death as she gave her life solely to save him. Bringing up the topic to his face is, however, a bad idea.   As a tiefling, he is a stark contrast to most other members of his family... one that many despise for his difference. The Aletheian Empire's ruling line has always been conditional on the blood of the outer planes remaining true, thus preventing non-aasimar members of the family from taking the throne. However, the wording is lax enough to allow for a tiefling ruler. Cyne's mother, Ceridwen Undria, didn't think to reveal her ancestry to Lord Andron Undria until after Cyne's birth, and the pure lineage of aasimars could not overcome the infernal blood in Cyne. He was born a tiefling, much to his father's horror. Thankfully, at the time of his birth, his uncle - Albion of Aletheia - was known as the Empire's Heir, and his wife was newly pregnant. As Prince Albion's plans for a large family were known, Cyne (or 'Cynos' as he was born) was allowed to live. Emperor Asterion of Aletheia personally intervened to ensure Andron didn't attempt to bypass Albion's request, much to Andron's displeasure, despite Asterion's own disappointment in having a tiefling nephew. This would set the stage for much of young Cyne's life.   His nickname, 'Cyne', was given to him by an amusing mispronunciation made by a childhood sparring partner after he'd read the young lord's name. Cyne preferred it, and found the puns his tutors made were preferable to their constant jabs at his heritage, so the name stuck. Prior to his ascension to the throne in 5625, Cyne's formal name - and name to much of the world - was Cynos Aneirin Elyan Undria. He was forced to change it due to the Aletheian Laws of Inheritance, but doesn't mind close friends' usage of the old nickname.

Physical Description

General Physical Condition

Cyne is a little underweight, but very much in-shape. What few scars he's kept are always hidden by a layer of illusion or by physical coverings. His tiefling aspects - his horns, his desaturated and too-cold skin, his pointed ears and slight fangs, and his glowing golden eyes - do not have any affect on his wellbeing aside from being points of prejudice.

Identifying Characteristics

The glowing red pentagram symbol of Asmodeus can be found on Cyne's wrist, though is almost always hidden by layers of illusion and leather to prevent its knowledge from leaking. A set of piercing red scars run down his throat, marking a near-mortal injury from his time on the battlefield where he first encountered Hopesbane. He hides them, too, but is well aware of the affect they can have on his tiefling physique.

Special abilities

Is a nightblade - heavily stealth-based and skilled with shadow magic, magical crafting, and various arcane spells. Has his own personal demiplane in the Plane of Shadow.

Apparel & Accessories

Wears finely-tailored outfits of black or grey, accented with silver, gold, and either blue or red depending on his business that day. Tends to keep his true appearance concealed with slight illusions that mask his magical accessories.

Specialized Equipment

Uses a sword made of umbrite gifted to him by the drow of Yuethin'tar, aptly named Heirsbane for reasons he keeps to himself. Decked out in magical items from various sources - elf-woven cloaks, a belt forged by the southern states, and the list only goes on.

Mental characteristics

Personal history

Cyne grew up facing the constant fear of assassination for simply being 'the royal fiend'. As such, he trained with skilled warriors and learnt how to avoid sight from an early age; as his magical ability showed itself, he sought out tutors in rare shadow-based magics to master this talent. This was how he first encountered the Shadows, though he didn't join until shortly after he reached adulthood.   When he reached the age of 12, his sister, Alysia, was born - and he began to express his first infernal characteristics. Whilst his blood had been known as infernal since birth, it was far harder to hide the glowing golden eyes that marked him as one of the Hells. Scared, his father forbade him from meeting Alysia until the girl was 6, and him 18. This first meeting was carefully watched for good reason - the annoyed 'teenager' acted rudely and dismissively towards his 'perfect' sister, exiting the meeting in a flash of shadow when Alysia demanded he join her for a tea party.   The two crossed paths on occasion, but didn't spend much time together until...

Alysia was stricken by the curse that would forever mark her as an oracle - he was the first to find her lying on the floor, having heard the strange thud in the neighbouring room, and refused to leave her side until she awakened.
Since that fateful day, shrouded in secrecy for the sake of Alysia's health, Cyne has been his sister's closest friend, confidant and guard - even though his own skills lend themselves elsewhere. Whilst their roles have drawn them apart in recent years, they maintain regular correspondence and often seek each other's counsel.   Aside from his familial relationships, Cyne's next years came with many lessons in appropriate etiquette, languages, magics, all sorts of history and politics... all alongside his continued Nightblade training. He spent multiple years at the Aletheian High Courts with the other members of his family, learning the ways of their ruling in case the worst happened to Albion Aletheia.   Needless to say, it did.
It was when he was in his 70s that the political education became relevant. An assignment from the Shadows had him infiltrating a dangerous cult that needed to be shut down. To prove himself loyal, he'd been forced to endure their contracts. Killing people for a price. His final contract was to slay a child and his father, leaving the mother alive. He did so mechanically, leaving no trace of his presence. It was a day later that he received word that his cousin and uncle were dead, that their souls had rejected attempts at resurrection. Being the only eligible outsider in the direct line of succession (as his father had been deemed ineligible, and his aunt refused to even be considered), he was now Crown Prince.   It was then that he realised his successful mission had only been so because his blood had prevented the protective wards from activating. That he'd caused their deaths and doomed his own fate. To this day, he has told none outside the Shadows about this... and hopes to take the secret to the grave.
  Over the years, Cyne has also endured many assassination and kidnapping attempts on himself, some of which were more successful than others, giving him much reason to keep his weaponry close and his scars covered by illusion.
Show spoiler
He has also taken numerous secret contracts for the Shadows, and led a team that contained Azyel Lathronon for a few years before requesting leave. His position in the Shadows is currently unknown due to his prior obligations to the Aletheian Empire.
He later allied himself with the adventuring group known as the Lost Ones, and aided them in many respects before their three-year disappearance. For a brief time, this granted him the position of Champion of the Lost Prince - a Fey Eldest. It was during this group's absence that Emperor Asterion passed away due to poisons developed by the evil Medimian Empire, and Cyne ascended to the throne as Emperor Aneirin.   After Iomedae's fall, his Championship became more of a burden as the shield of Tenaerul locked onto his magic and nearly killed him. The Prince of Hell, Asmodeus, learnt of this and offered to save him - but unbeknownst to Cyne, his sister was also involving herself with Asmodeus. Cyne accepted the deal - and Alysia became Asmodeus's Champion briefly before killing herself to permanently repair the Tenaerul shield and save her brother. Cyne then became the new Champion, unaware of his sister's death until he visited her to confirm. In the brief time since Alysia's death, the Emperor has already been observed to have become more stoic and withdrawn. Whether this change is permanent or simply part of the grieving process is unknown, though the increased presence of the High Priestess suggests the latter.

Accomplishments & Achievements

Emperor of the Aletheian Empire and a war hero of the same. Kingslayer, for his refusal to allow the King of Ordan to murder him. Invented the Books of Instant Transmission - a series of books enchanted to pass messages instantaneously. Liese Celadrion has since improved upon the enchantments to allow limited transmission of items and liquids.

Failures & Embarrassments

Couldn't protect his sister, or the others that he cared about.

Mental Trauma

Severe depression and post-traumatic stress disorder. Heavily blames himself for what happened to Alysia, and to certain others. Still suffering the effects of

Personality Characteristics


Wants to protect his sister from the cruelties of life and become skilled with his blades and magic. Secretly desires a neutral, politics-free life of adventure, but knows that he will never be granted this wish. Wants the best for his people, no matter the cost to himself.

Savvies & Ineptitudes

Talented blademaster, illusionist and shadowcaster. Useless at completing paperwork and being where he's expected to be. Surprisingly prone to enchantments.

Likes & Dislikes

Likes isolation, shadow magic, illusion and sneaking around (and adventuring in general). Also likes annoying Ashlyn Alarian, the colours green and gold, red wine and esoteric knowledge. Prefers fine cuisine and expensive fitted clothing.

Virtues & Personality perks

Dextrous, quick to act, and incredibly sarcastic. Attempts to stay neutral in conflicts unless they involve him or threaten to harm those he's sworn to protect. Deadly if he perceives a threat to his 'charges'.

Vices & Personality flaws

Reckless. Doesn't immediately think of how his personal life and actions might affect his political life, but is trying his best to fix that. Often suppresses emotions instead of dealing with them, particularly in stressful situations. Inwardly depressed, but has developed significant skill at hiding it.


He stays immaculately clean and has perfect manners, but tends to get lost in readings and research. This results in a terrifyingly messy study until he comes to his senses and restores it to normal - or has a servant or family member interrupt him.


Family Ties

  Great-great-great... etc. grandnephew of Ashlyn Alarian.

Religious Views

Hides his religious beliefs, but is a follower of the Lost Prince due to their similar views.

Social Aptitude

Refined manners and smooth, diplomatic behaviour in political situations, but sarcastic and more casual around those he doesn't feel the need to stay 'refined' around.

Nicknames & Petnames

He tends to call her 'grandmother' and similar family-based nicknames.

Relationship Reasoning

Ashlyn doesn't approve of his methods. But still loves him as family. Cyne doesn't care for her fervent religiousness, nor does he care so much about the law. And he finds her naive & paranoid nature to be endlessly amusing. However, he admires her might in battle and ability to uphold the law no matter what, and essentially views her as another sibling (given their similar mental ages).

Towards Alysia Undria




After a rough start, the two siblings bonded over Alysia's curse and became close friends. They trust each other above all, and Alysia sees him as her closest confidant. Whilst they don't get to spend too much time together, they write often, and she often wishes she could ease some of the burdens he's holding away from her.

Relationship Reasoning

Other than their blood relationship and general friendship, they're mutually good for one another. Alysia has helped Cyne recover from wounds many a time, putting her divine powers to use. In turn, he handles diplomatic situations so that she needn't be involved, and uses his shadow magic to prevent light from reaching her during her attacks. She watches out for anything dangerous coming his way, and he defends her from would-be captors - or suitors, if it's necessary.
