The Maraid, Book VIII, Chapter 1

After the Scatter, the frontrunner for the Kellship was Irxis, Wolf Baroness. While Skolas and Parixas scrambled over the Kaliks servitors, Irxis secured the command of the Orbiks servitors.

Their history is still unclear, but the Orbiks originate with either another Fallen house—perhaps one that the Wolves absorbed long ago—or a modification of the Kaliks servitors. Either way, the Orbiks servitors held permissions on Kaliks servitors, which allowed Irxis to wreak havoc among her rivals' forces at the start of the Reef Wars.
