The Red Collective did not gather a random group of qi cultivators and sent them off to Ves before calling it a day.
Whoever was in charge of setting up the Moloch Squadron put a lot of thought behind the selection of personnel to reinforce the Bluejay Fleet.
In hindsight, it shouldn't have been surprising that the collies sent a remarkably competent formation master to Ves who specialized in scrying.
This was because Ves was too important of a leader and innovator to remain vulnerable to this novel method of remote observation.
Even if Ves was confident enough that his Spirituality or his companion spirit would have been sensitive enough to detect and counteract such attempts, they might not be able to prevent all scrying attempts if they remained unaware of this potential method of intrusion.
Besides, Ves was not the only target of scrying. What if an unknown party tried to spy on his wife, his children or the other members of his clan?
