Archangel Ascher

The Archangel Ascher, also known as the Father of Lies, was one of the fallen archangels mentioned in the Book of Chihiro of the Holy Writ.

According to scripture, Ascher sided with Shan-wei when she rebelled against the Archangel Langhorne, and created a false history of the world of Safehold, leading those who reat it to damnation.

He (or she) was actually based on a historian of the Operation Ark command crew who supported Dr. Pei Shan-wei at the Alexandria Enclave.
