Artholath gave a little smile, which was easily lost on his demonic face. He had an idea... the souls as they were didn't quite pass the level of being completely demonic. If he put in a little more than just their souls... but a little of his own... then they would be fully demonic in nature.

With this in mind, he stepped between the bodies and inserted the souls as he had done with the others, at the same time letting little portions of his own go, something which was a little visible as he strained to release just enough to get the job done. He stepped back and watched when he finished.
