Shosuro Maru

Shosuro Maru was a courtier of the Scorpion Clan.

Champion of Bushido
She was one of the seven Champions of Bushido, more exactly the champion of Makoto (sincerity). Her yojimbo Bayushi Muhito was one of the remaining six champions. 

Oracle of Obsidian
She became the first Oracle of Obsidian after the creation of the Obsidian Dragon to balance out the Jade Dragon and its Oracle.

Investigating the Spider Clan
Maru aided Scorpion Clan Champion Bayushi Paneki in 1170 with his investigation into the Spider Clan. Maru provided intelligence for Paneki's agent, Bayushi Eisaku. 

Voice of the Moon
After the Obsidian Dragon challenged Lady Hitomi for the position of being the Moon God, and won, Maru became even more powerful. Now the Voice of the Moon, she began to walk to the Imperial City Toshi Ranbo, talking to some selected people along the way.

The Obsidian Hand
In a sake house in the Crane city of Tsuma, Maru joined Kakita Kensho-in at her table, where they discussed Kensho-in's history of lies, deceit, and murder, all in the name of the Crane Clan. Kensho-in was horrified at being forced to live through three her three most significant sins all over again thanks to Maru's powers. Maru explained that she admired Kensho-in for embracing her violent and murderous nature and honing it as a weapon for the Crane. She then turned Kensho-in's right hand into the new Obsidian Hand. 

The Celestial Tournament
Upon arriving at Toshi Ranbo, Maru and Omen announced to all in Shosuro Jimen's court that it is the will of the Heavens for there to be a new Emperor, who will be chosen through a new Celestial Tournament similar to that held by the Kami back at the dawn of the Empire.
