He waves a hand perfunctorily. "No, no, your explanation gave me enough, I think, to understand. You left because you didn't like the lot assigned to you by your tribe. That is something I can understand well enough." His interlocutor is clearly uncomfortable discussing his place of origin, and the tattoos made it clear that Sharlayan was as much his homeland as anywhere. Ultimately he only asked out of habit, to know how not to offend: it is a paramount part of his role as the liaison to so many foreign interests with the scions. Being himself a Miqo'te, unaffiliated in most people's minds with any large nation-state, has made it easier to pass himself off as a neutral arbiter, especially here, in the East. In this case, however, the interrogation seems as likely to cause offense as prevent it, so he would simply have to operate as though the man before him were a Sharlayan.
Perhaps honesty is best here. "I just wanted to understand your culture well enough to be polite within it. Each has its own standards of courtesy, as I'm sure you're well aware by now. There is no need to discuss something so uncomfortable. You'll just have to afford me some grace is I behave unexpectedly." He flicks his ears and smiles: a friendly gesture. "Or I suppose—since you're here to ask me a favor—I have the upper hand for the moment, and can make you operate according to mine instead." He chuckles and grins again, to be clear that he is joking.
"Your questions are no bother, friend. Certainly it would be hypocritical for me to mind them," he says, then, after a moment, sighs despite himself. "To be honest, you're among the first to even inquire, even in my several years floating between the cities. Gridanians don't want to know, and nobody else can differentiate us from our rivals." He shakes his head at the admission. "It doesn't matter, of course. I'm not here representing the shapah, really." He smiles again, weakly. "If anyone, I've been mostly representing Doma, lately."
