[Indeed, throughout the meeting there has been a silent, blank-eyed girl standing mostly hidden behind Zelda's chair, and as the conversation progresses, Zelda beckons her to come around. Those sitting nearby or those with particularly sensitive hearing may hear snippets of the whispered, and admittedly rather one-sided conversation that follows; things like what do you think? and would you be okay with that? and she won't hurt you, you can trust her. The girl, for her part, mostly responds with vague tilts of her head and glances between Zelda and Ginia (and Zelda's own eyes trail briefly after Caster as he makes his exist), but eventually there's something that could be construed as a nod, and Zelda decides that's going to have to be good enough.]

Ginia, Tamako is willing to allow you to attempt to name her if you want to try.

[Which might be up in the air now, with Caster gone. But, well. Progress demands sacrifice.]

Your incantation would be as follows: "My name is Ginia. Grasping thy true name, I bind thee here. With borrowed name, I dub thee my servant. The name answers, the vessel to sound. I call thee as my divine instrument." You would then call out the name you will give her, followed by the vessel drawn from that name, and then finally call for the vessel form itself. To release her afterwards, you would simply say, "I release you," followed by the name you gave her.

[Hopefully that all makes enough sense. She doesn't want to offer suggestions for names in case that affects how the spell would work for Ginia.]
