Kesdaeth was once one of the amesha that betrayed their empire and passed to The Other Side. Centuries ago, Kesdaeth, sick of the war and the divisions, resorted to the Law of Balance and declared himself neutral. He then went to Earth and started his life as a common human until today, when he is known as Grigor Kasday. Unfortunately, one day he started losing control of his powers, unable to maintain a human form and avoid hurting others. Harlan, Kurjak and Tesla were sent to investigated on this homicide spree, but even Lady Nahema and Semyaza were on Kasdaeth's tracks, to bring him back to their side.
