Eir, the Keeper of Order

"ORYX, SET YOUR HOUSE IN ORDER."

- Eir

Eir, the Keeper of Order is one of the five Worm Gods, ancient beings second only to the Darkness itself in the hierarchy of the Hive pantheon. When Crota unintentionally brought the Vex into the Hive's Ascendant Realm, it was Eir who came to Oryx and demanded that he stop the Vex and keep his spawn in line.

Trivia

 * Merok uses Eir's name as part of his title.
 * After Oryx slew Akka, who was also the strongest Worm God, Eir presumably became the Taken King's patron god.
 * Based on this, it could be that Eir became the strongest Worm God after Akka, being more powerful than Yuul, Xol, and Ur.
