Around a decade prior to the events of Galaxy Angel, Gerald would have an affair with the White Moon's high priestess, Shatoyarn where she sired him a daughter, Shiva. However, for political reasons, this was never publicly revealed and Shiva's identity was kept as a male. Around this time, Gerald would also banish Eonia to the frontier as his dangerous idealism for expansion began to scare the higher ups.
Not much is known of Gerald personally other than Tact recounting that he was a respected and popular ruler. He was killed along with all the other royal family during Eonia's coup d'état,.
