[As the vision fades, he watches them go their separate ways. Childe, presumably back to an office or somewhere else in the bank, and Lumine, leaving the bank. His heart is pounding, something he hadn't noticed while viewing the vision, confused as to why this time they had watched it instead of living it like the last one.

He barely realizes she's asked him a question, focused on the fact that Childe has confirmed that he's from Snezhnaya too. There's so much about that that bothers him. His siblings have the same names, the only difference is that Childe is Childe and he's Ajax. Is that his actual name? What is going on...]

...What? Oh...sorry. I was lost in thought for a moment there.

[He rubs his head, thinking.]

I remember reading that Childe was some sort of general in the military when he was alive. But now that I think about it, his title was Harbinger, so I'm guessing that's what a Harbinger is. One of the most powerful people in Snezhnaya, widely feared for his battle prowess.

[He shrugs- that's all he has, right now.]

I didn't have too much time to look deeply into it, but that's the little I gleaned from a few historical websites. I think the paludamentum across his chest suggests that's true. That garb was very much militaristic, don't you think?
