Oryx being an opposite of the traveler would make perfect sense. Oryx is a god to the hive like the traveler is to the guardians.Oryx motive is to spread darkness, but he can't with the travelers influence on the dimension. This gives Oryx a motive to destroy the traveler, but in order to do that, he must physically animate himself in order to lead his army to spread darkness. This is how "Crota Son of Oryx" was born, piece of Oryx in the inbodiment of a knight. This would make so much sense because Crota's soul looks like a shard, a shard of Oryx, and when activated it summons Crota.
