A wise minister wanted to meet a wise king and a wise king wanted to meet a wise minister.
When these two people who have the same desire meet with each other, the synergy between such people is undeniable.
And that is why Aeryon trusted Mayeux so much and why Mayeux would do his best to assist his lord.
Mayeux met Aeryon and these two people complemented each other.
Aeryon has grand ambition and Mayeux wanted to fulfil that ambition of his lord.
Mayeux kneels and put his hand on his heart and pledge allegiance to Aeryon and Aeryon pull him up, accept his allegiance and since then these two have been close like birth brothers.
They met night and day and whenever there is something that bothers the mind of the Kan, he would summon Mayeux.
Mayeux is also the only person other than Belarion that is allowed to bring weapons and to rush into the tent of the Kan without notification.
Mayeux is loved by the Kan and his soldiers.
