Obsidian Dragon

The Obsidian Dragon is the tween of the Jade Dragon. Created from the essence of Onnotangu, the deceased Lord Moon, the Obsidian Dragon was born to correct a great imbalance created by the actions of the Jade Dragon. The Obsidian Dragon is not a creation of the taint, but it is not less sinister. It represents the opposite of his tween: vice and sin, and it promotes dark qualities in mortals in order to help them achieve greatness. Those who master their vices become stronger, and those who do not are destroyed.

The Obsidian Dragon appeared recently to Isawa Angai, through the actions of Agasha Miyoshi, priestess of the Temple of the Seven Dragons. The dragon told Isawa Angai that it was searching a mortal to become its oracle, to get more power in Rokugan and correct the imbalance created by the actions of the Jade Dragon, whose oracle is the Crab Clan shugenja known as Omen. Isawa Angai was not the indicate person, so the dragon asked her to name a person that could serve as its vassal in the mortal realm, and become the Oracle of Obsidian that could foment vice on a scale unprecedented in the Empire. For reasons known only to her, Angai smiled and whispered a name to the beast, which promptly disappeared.
