My true form can function similarly to what I believe humans would call a... wavelength, in terms of the function of heat, sound, or light. But significantly vaster and more complex than any of those. It is a wavelength of intention.
And as we are intended to be the guardians of humanity, I am designed to be able to locate any human anywhere on the planet, save those that are hidden from my sight. She is not of my world, but if I can get a sense of her, and if she still exists in this world, I will find her.
