Age

Umm?

Yerin herself wasn't sure how old she was,
but twenty had to be about right.

-Uncrowned

Yerin doesn’t know her exact date-of-birth, because of her traumatic childhood. She thinks she’s about a year older than Lindon. In Uncrowned, book 8, Naru Saeya suggests she is about 20.

Appearance

In book 1, Unsouled, Yerin is very thin, and shorter than Lindon. She’s scruffy, like she has spent the past weeks camped out in the woods. She cuts her own hair with sword madra in a perfectly straight line to minimize its interference in combat. Initially, she wears a tattered black sacred artist's robe with a thick red cord tied around her waist. It’s made of blood spirit. Her skin is covered in thin white scars from practicing the Endless Sword technique. In book 6, Underlord, she advances to Underlady and her body is reforged in soulfire, so her scars disappear. Encouraged by Akura Mercy and Lindon, she allows her hair to grow past her shoulders but continues to cut her bangs short and straight.

Personality

Yerin is /was dedicated to her beloved master, the Sage of the Endless Sword. Now that he’s dead, she clings to his teachings and his memory. Also, after her master was murdered in Sacred Valley she’s been suspicious of supposedly kindly strangers. However, once she gives her trust, she is totally loyal, especially to Lindon. She is an intense person, brave but not showy, without an ounce of self-pity. Her words are few but honest; her speech is habitually pithy and straightforward, but not mean-spirited. She doesn’t know when she was born. She cannot read or write, but she is intelligent and frequently comes up with dry-as-dust analogies, metaphors and similes. She despises her Blood Shadow — a piece of the The Bleeding Phoenix — as it has murdered many innocent people, including her entire family. She fears being alone. She lost her entire family at about age 7 (see Skysworn). She lost her master at about age 16 or 17. She doesn’t want to lose anyone else that she calls friend or family. She values her relationships with Lindon, Akura Mercy, Ziel, Little Blue, Orthos the Sacred Beast, and Eithan Arelius.

Biography

Yerin was known to be a genius in her hometown before everyone was slaughtered by a Blood Shadow belonging to The Bleeding Phoenix. She was only seven years old.

The entire purpose of the Blood Shadow was to steal power by killing or possessing others and bring that power back to the Bleeding Phoenix, but Yerin hadn’t allowed hers to escape. Not since it had killed her parents. (Wintersteel chapter 16)

At only seven years old, she held the bloody thing back and stopped it from attempting to kill the Sage of the Endless Sword. Although he was completely safe, he was impressed by her willpower and natural talent, and chose to take her on as his apprentice. He challenged her and caused her many injuries and scars, taking her around the continent for training. When Yerin was about 16 or 17, he took her to Sacred Valley and went into the Labyrinth via the Ancestor’s Tomb on Mount Samara, intending to ask Subject One how to free her of her Blood Shadow. However, treacherous elders and jades poisoned and killed him. After his assassination at the hands of the Heaven's Glory sect, she was driven out of the temple they were using as a base. She met Wei Shi Lindon, avenged her master, and used his Remnant to ascend from Jade to Lowgold. About a month later, she met Eithan Arelius in the Desolate Wilds of the Blackflame Empire. He has guided her and Lindon ever since then. She joined the Skysworn (Organization) to fight The Bleeding Phoenix and its Dreadgod cult. She competed in the Uncrowned King Tournament. She also helped evacuate Sacred Valley and also helped to battle a monarch in the Labyrinth.

Powers and Techniques

Yerin is a top-notch sacred artist on the Path of Endless Sword who is consistently able to defeat opponents of a higher level of advancement, or multiple opponents of her level.

Notable Opponents and Duels

While a Lowgold in Soulsmith, Yerin was able to defeat 3 other Lowgolds who tried to attack Lindon. In Blackflame, Yerin as a new Highgold was able to give Jai Long, a Truegold, fear for his own safety until he decided to escape. As a Truegold in Underlord, Yerin (along with her newly advanced Blood Shadow clone) was able to simultaneously fight attackers from the Seishen Kingdom, Underlord Prince Kiro and Underlady gardener Meira. The outcome was that Kiro was heavily wounded and the underlords had to escape. In the Uncrowned King Tournament Yerin duels several contenders. Most notably she battled blindfolded against Altavian Arelius from House Arelius, and then against her best friend Wei Shi Lindon Arelius, and also against the gold dragon, Sopharanatoth.

Innate Abilities

Steelborn Iron Body: Yerin's special Iron Body grants her superhuman strength dramatically beyond that of a normal Iron Body.

Sword Sage's Remnant: Yerin is bonded to the Sage of the Endless Sword's remnant. This grants her multiple other retractable limbs that end in swords, as well as access to some of the Sage's memories.

Blood Shadow: In Underlord, Yerin gains the ability to release her Blood Shadow, who is able to fight as an independent copy of her with all of her skills and abilities. She is well coordinated with her Blood Shadow.

Netherclaw — To defeat the gold dragon Sopharanatoth, Yerin merges with her Blood Shadow Ruby, near the end of book 8, Wintersteel. She also advances to Herald. This gives her more strength and oceans of blood madra. She can now employ Netherclaw.

Moonlight Bridge — a tournament prize. She can travel anywhere instantly.

Path of the Endless Sword

Yerin was taught the Path of the Endless Sword by The Sword Sage, Adama.

Path Techniques

• Flowing Sword (Enforcer): sword aura is collected from the surrounding area with every movement of the sword. This technique strengthens Yerin's strikes as the fight progresses.
• Rippling Sword (Striker)sends out a wave of sword aura it can be launched from her remnant arms at her back
• Endless Sword (Ruler): waves of sword madra emanate from Yerin, cutting anyone and anything caught nearby. Any bladed edge caught in this technique will emit sword madra of its own, setting up a potentially deadly chain reaction. In Ghostwater, Yerin learns to control this better.
