"Irregular Tamers Guild"

When Ainsley asked like that, Evan paused before patting the baby's head, acting as if he's her dad or something. 

"Well, you should have known about the sworn ally matter that my family declared not too long ago?" 

"Oh, twat, yeah! It hewlps me a wot." Ainsley nodded. 

"Good then. But that's still a one-sided statement. We need your side also to make the same statement and sign a few documents." 

Evan continued his explanation about the sworn ally thing. 

"In addition, the family head of that generation has to swear an oath to each other. That's when that family can be declared as sworn allies." 

Of course, once the family had changed, the oath would be nullified, and that's why the new family head had to make another oath if they wanted to keep the relationship at the sworn ally level. 

"You know about a sworn ally, right, Ain?" Evan stopped explaining and suddenly looked down at Ainsley.
