Andrew was well aware in his heart that the Desert Speaker Rose's act of "driving beasts to chase people" was just a test.
So just handle it normally, rescue the people, kill that Desolate Beast (although live capture was initially intended), and that's it.
The alarm has been lifted. The desert returned to tranquility once more.
After a tentative contact between both sides, a retreat was made.
The others might not have expected Andrew's side to react so quickly, rescuing people and killing beasts so efficiently. Or, perhaps they didn't expect Andrew to actually use the connection between the Desolate Beast and Rose as a way to say hello for a strong response.
In short, Naros didn't seem to make any further actions for the time being.
Andrew also held back and didn't pursue further recklessly.
"Are we going back now?" Ivan asked.
