Curiosity

Aeryon summons puts Garron in a difficult position, knowing that he must comply to avoid potential repercussions for his daughter Ayera and for his tribe

There is always a chance that Aeryon could turn this in some kind of way as some cause to attack the Utgard tribe. 

Garron is a very cunning man, brutal and manipulative. He also seems very heartless. But even he has some weakness. 

And that is Ayera. His daughter. Her mother died early and Garron loves her very much. And Ayera resembles her mother in appearance

But in his personality, she resembles him more. 

He might send Ayera to Aeryon to spy on him and even assassinate him. But…it was also a kind of protection measure

The moment Aeryon had chosen to take down Xewa and Ghar tribe, Garron could feel the wind of change is blowing in the Great Steppe.
