Cassandra Richards was the wife of Nathaniel Richards, and former ruler of Other Earth (Earth-6311). Richards arrived on Other Earth using a time machine that was designed to send him into the future, but instead sent him to a parallel world. This Earth had been devastated by a war that occurred centuries before, between the people of the Earth and the human colonists of the Moon, ending in the destruction of the Moon itself. Uniting the war-torn planet, Nathaniel Richards formed an alliance with a bird worshiping matriarchal society. He gave the leader of this society the information to better her people and develop advanced technology, including flying, metal birds that they rode on. In gratitude, the leader gave Nathaniel her eldest daughter to marry: Cassandra. Cassandra begat him two children, an unnamed son, and Tara.
