Crux Australis is not all-knowing. Astrolabe and Baryl assist by being closer to the Eastern and Western (respectively) groups that are not near Crux and keep an eye and ear out for news or issues that Crux needs to be aware of. Astrolabe and Baryl will be Baronial Heralds in their own right who agree to take on this small additional supervisory role. Former Cruxes and/or Crux Deputies might also be considered due to the expertise earned from those roles.
