[Despite urging Noctis to go in his stead to seekout "Hope" and pledge his allegiance, Regis decides to do so as he originally planned. He doesn't trust these alleged deities and he trusts them even less with his son. This is why the old king decides to submit himself to their divine will if only to assist in aiding the others return back to Eos.

So after a brief moment of hesitance on his part, Regis finally speaks. Forgive the old man for his sense of formality here. He's unaccustomed how to address a deity and his anxiety is getting the best of him. Nevertheless when he speaks, Regis actually doesn't give away his nervousness at all. He sounds assured and confident like a king should.]

Hearken unto me, God of Hope. I wish to speak you regarding matters that effect us both but first allow me to stand on ceremony and introduce myself. [He pauses for a brief moment before finding his nerve again.]

I am Regis Lucis Caelum the One-Hundred and Thirteenth of my name, the Former King of Lucis, King of Light and Guardian of the Crystal. I have forged pacts with deities in times past but this will be the first time I've met one of your kind.

[Deities who take the form of mortals? Quite the oddity in Regis' book. Nothing like the Six he knows well.]

At your earliest convenience, I would like to speak with you.
