I was actually thinking that True Names should have some kind of power. Perhaps not complete control, as that would be OP, but some power. For instance, if someone knew their own True Name, they would become more capable of controlling their physical body and spirit, making them able to wield magic with more skill and to carry out more physically difficult activities more easily.
If someone else knew your True Name, they could hinder your ability to learn, make your body more sluggish etc. This isn't so important for gods (they can do that anyway) but would be interesting in the interactions of mortals with one another.

I would say that this wouldn't apply to gods and demigods.

I was planning on giving the True Names a certain power. In all honesty I was envisioning something more mental. Like one could access past memories through the True Names. Or increase focus through meditation, temporary 'separating' body and soul which could give certain insights into how the world of magic (and maybe the Gap?) worked. Those are all just mere suggestions.
