One thing to note now--I wasn't very satisfied with Glimmer's dialect myself, and DavidB's comments tipped me over the edge. I'm now thinking of going with something more like this:
Aether. a voice said in her mind. It was light and airy, like a voice carried on the breeze, and felt lethargic. King
Yunmi glanced down at the rose-colored crystal embedded into her forearm just above her wrist. King Theus? She thought.
Aether. the voice responded, dull, slow. As always, Glimmer's voice was accompanied by images in her head, filling out the single word. This time, the image was of a dark black crystal set into a man's hand. Theus's hand, which had been covered by a glove when Yunmi had met him.
So Theus does have an Aether, Yunmi thought. Did you speak to it?
Unresponsive, her Aether replied. Old. In her mind, Yunmi saw the Theus's Aether as Glimmer did--as a thing ancient, barely capable of putting out Aetherpulp. A thing tired, yet forced to continue living on, attached to the king's flesh.
Also, I don't like Glimmer's name, so consider that a placeholder right now.
