The Kings fall raid description reveals that oryx had a master, that he was a servant to. "How did you take (or rather, untake) the blighted light that Oryx gathered to offer in sacrifice akka-" So we have the name of his master How do I know it is his master? If you read the hive 4 card, you'll see that toland discovered the names of the hive gods, xol, yul, Eir, And Ul.
