Sathona was the middle child of the Osmium King, who sought to consume the "Mother Jelly" to live 10 years beyond the traditional 10 year life span of the Krill.  Dubbed as the "Most Cunning" of the 3 sisters, she later became Savathûn, the Witch Queen, God of Cunning, after ascending her species to immortality and becoming the Hive.
