The Imperial Families were the families of the Emperor and his closest followers. The original Imperial line was founded by the Kami Hantei, and the families by his followers Seppun and Otomo. Miya was granted a family at the beginning of the reign of Hantei Genji. Toturi became emperor following the death of Hantei XXXIX during the Clan War and the end of the Hantei Dynasty. The reigning emperor was referred to as tenno, or 'Heavennly Sovereign'. During twelve centuries the Hantei were the ruling house of the Emerald Empire, ruling as the political head of the nation as well as the leader of the Rokugani religion. The heir assumptive was known by the title of Kotaishi and educated by the foremost Shintao priests in the Empire. Through the Ritual of Abdication any Hantei who did not ascend to the throne stepped aside, renouncing their name to clear the line of the true Emperor. They usually took the Otomo family name. In the 12th century the Scorpion Clan Champion Bayushi Shoju discovered an ancient prophecy stating that the last Hantei would bring about the return of Fu Leng and the fall of Rokugan, and he decided that it was his duty to the Empire to prevent this. In 1123 he staged the Scorpion Coup in an attempt to assassinate the Emperor Hantei XXXVIII and his son and only heir. The son survived however, and after the death of Shoju became Hantei XXXIX. His rule would not last long, as he became quite sickly, and when he was near death he became possessed by Fu Leng. In 1128 the Second Day of Thunder took place, and when Fu Leng was defeated by the Seven Thunders, the Hantei line came to an end. Unknown to almost everyone in the Empire, including the Emperor himself, Hantei XXXVIII had another heir, Daigotsu. Daigotsu was the unborn child believed to be killed by Bloodspeakers. The child survived and was raised by the cult, eventually becoming the man known as Daigotsu and the Dark Lord of the Shadowlands. [6] Also unknown to nearly all within Rokugan was the fact that the immortal sorceror Iuchiban was also heir to the Imperial Throne. Until his death in 1166, there were at least two possible claimants to the throne.
