Chengyuan Emperor

The Chengyuan Emperor, known in-story while alive as simply His Majesty the Emperor, is the current ruler of the Zheng Empire, and the head of the Zheng Imperial House at the start of the story. He is the 8th Son of Heaven of the Zheng dynasty (discounting disavowed rulers).

Names
As is the case for Chinese Emperors, the Chengyuan Emperor is known by many names. The designation Chengyuan 承元 is actually his era name.

The Emperor's given name is in fact He Huan (何焕), but this name is forbidden from being mentioned due to the naming taboo.

Background
The future Chengyuan Emperor was the 3rd son of his father, Emperor Mingxuan of Zheng (also known as the Datong Emperor).
