The Archangel Grimaldi was one of the fallen archangels mentioned in the Book of Chihiro of the Holy Writ.

According to scripture, Grimaldi sided with Shan-wei when she rebelled against the Archangel Langhorne, and Grimaldi's twisted version of the healing teachings of the Archangel Truscott became the cause of pestilence.

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