Chisei

Chisei (CH or CE) is a period of the Topein calendar that traditionally began on 1102 NE (1 CH) with the coronation of High Priest Kangxi as Emperor of Topei, and continues to the present day. After the death of Kangxi in 1162, it has fallen into disuse and has been mostly replaced by the old Nenrei system.

History
Chisei was proposed in 1148 by Harrakaas, a Vahian ambassador in the Topein court. The idea was endorsed by several members of the court and later endorsed by Prince Akio.
