Ardannis, Turn 2.4, Group 31
Looking at Rtskink, Ardannis replies How Oque make Quax? Oque can make Quax, Ardannis can make rock disappear. He grins.
Turning back to the rest, How Ardannis help Oque? Ardannis help Oque trick beasts, hide from beasts. Oque get food more easily, not worry about beasts.
SpoilerI don't know if it's a stretch to say he observed them long enough to see Quax in use - it doesn't seem like one, but I'll edit the post if it's too much.
