Bayushi Sozui

At first glance, Bayushi Sozui was a impressive and refined Scorpion Clan courtier. In fact, she was a skilled assassin, formed by the Shosuro. She was also a servant of the Lying Darkness.

Birth and Childhood
Bayushi Sozui was born into the Kakita family of the Crane Clan. In 1100, when she was a child, she was supposed to be exchanged for one year with a Matsu child as an act of goodwill. Both the escorts were slaughtered by agents of the Scorpion Clan, and the children were stolen in an effort to sow animosity between the Crane and Lion Clans. (The Lion child was named Matsu Shimesu.)

Sozui was raised as a Scorpion. Conditionned and shadow-branded by the Shosuro family in order to make her forgot her name and her origin, she became very effective as an infiltrator agent, but the process helped the Lying Darkness to make her one of its own.

Kenson Gakka
In 1120, she was ahead of a plan to get back the city of Kenson Gakka from the hands of the Lion Clan. Her goal was to increase the tensions between the Crane and Lion Clans. (It's not clear if this was a side effect desired by the Scorpion Clan or if she was at the time already acting for the Shadow). She assassinated Akodo Ikare, general of the place, and replaced him by a Shosuro actor. After the kidnapping of Ikare's son, the false Ikare ordered the slaughter of the Yaruki Jukko monastery, who was receiving Crane monks at the time. Amongst the survivor was Noshin the shinpu of the monastery, formely known as Soshi Tankenka. Ultimately, the Scorpion Clan plan to take back Kenson Gakka failed, but the slaughter of the monks did increase the tension between the Crane and Lion Clans.

Legacy of the Forge
In 1120, along with the traitor Kitsu Goden, Sozui manipulated the tensions between the Lion and Crane, using spirits from Toshigoku to possess samurai from both Clan to push them into a war. Eventually, she was exposed and defeated by a small band of samurai.

Scorpion Coup
She was in Otosan Uchi during the Scorpion Coup, where she acted to increase the instability and chaos in the city in order to facilitate the coup. She tried to bring on and form an army for the Lying Darkness. She tried to recruit from a Yaruki Jukko monastery, created in Otosan Uchi after the Kenson Gakka massacre.
