Yaeko

Moto Yaeko became a Dark Moto and Akutenshi. He later founded the Shrine of Tenno Heika as Yaeko.

Akutenshi
Moto Tsume led the Moto into the Shadowlands in 825, and Yaeko followed the ill-fated charge as his shireikan. He fell to the coruption becoming an Akutenshi.

Concealed Cult
One hundred years later he returned to Rokugan and built the Shrine of Tenno Heika, founding the Servants of Heaven, a concealed Maho-tsukai cult. The recruiters, only one or two per year, were initiated into maho and soon transferred to the Shadowlands to become akutsukai.
