From Destinypedia, the Destiny wiki
The Helium King was the ruler of the Helium Drinkers, a Krill nation neighbouring the Osmium Court and raiding it every day. He conspired with Taox to assassinate the Osmium King and his three daughters in order to install Taox as a puppet regent. The princesses fled the Court and swore vengeance upon him, with Sathona in particular vowing to kill the Helium King and raise spawn on his corpse. It is unknown, but highly plausible, he died before or during the skirmish when the siblings were retaking their home, or later to the God Wave.
