Yeshin aren dar Orenar

“Frightened of  me, you mean...I should have never gone through with those beheadings. Worked far too well, if you asked me.”

Warlord of the Oren-yaro lands, he was actually born the youngest son and did not know he would inherit the title until late into adulthood.

This meant that Warlord Yeshin grew up mastering skills meant to support his brothers--swordsmanship, archery, horseback riding, and soldiering. When he found himself outliving his brothers, he quickly took pains to educate himself, calling on scholars to help him learn how to rule.

As he rose to power, Jin-Sayeng grew to see Yeshin as a true representative of his people's reputation: strong, dutiful, and steadfast. They also saw everything they feared of the Oren-yaro in him: aggressive, impatient, unforgiving, and with a penchant for recklessness. This made Yeshin an imposing figure, one to be wary of. During the War of the Wolves, he was called Yeshin the Butcher, alluding to the thousands of innocents he cut down on his path to power.

Aina's Breath
Warlord Yeshin is introduced in Aina's Breath, when he is coming to terms with his second wife leaving him for another man. His first wife died of childbirth, but left him with four strong sons: Taraji, Senjo, Lang, and Shoen.

He seizes a convoy Dragonlord Rysaran has ordered him to keep an eye on, suspecting it was more important than his liege made it appear to be. He learned it was in fact what Rysaran believed to be a dragon. Yeshin breaks the creature from its cage, which escapes and destroys almost everything in the keep, including Yeshin's sons.

Though half-mad with grief, Yeshin himself manages to trap the creature in the debris while barricading the gates, indirectly causing a famine in Oren-yaro. This attracts the attention of both Sume Kaggawa and Ichi rok Sagar, whom Rysaran had sent to Oren-yaro to investigate. Sume extracts the truth from Yeshin, who blames Rysaran's carelessness.

Sapphire's Flight
Yeshin recovers from his ordeals at the end of Sapphire's Flight to declare war against the Ikessars and seize control of Jin-Sayeng for himself in recompense for his sons, leading to the War of the Wolves.

The Wolf of Oren-yaro
Yeshin dies of old age sometime before The Wolf of Oren-yaro, but shows up in flashbacks and memories of his daughter, Talyien.

The Ikessar Falcon
Talyien's flashbacks grow more intense as she slowly uncovers the extent of Yeshin's involvement in her brothers' deaths and the true nature of his war.

Legacy
Far from bringing peace, Warlord Yeshin's actions caused turmoil in Jin-Sayeng that would last close to three decades. His daughter Talyien aren dar Orenar's rule is marked by dissent and further fracturing of alliances throughout the land. Over a decade after his death, his shadow continues to haunt Jin-Sayeng.
