At some unspecified point, Rain had realized his true heritage, that he was an illegitimate child conceived from the affair of the Edenian protector god Argus and an Edenian woman named Amara, making him half-god and half-Edenian. Rain had always assumed both of his parents abandoned him. In his non-canon MK11 ending, he uses the Hourglass to reveal the truth: Argus wanted to get rid of Rain out of shame, and so lied to Amara claiming that Rain is a stillborn. Argus threw him away to live among the peasants of Edenia. Amara's heart became broken, and she eventually died out of grief for her child.
