Opening with the eyes - original and intriguing. The soul catcher, the aura, the unchildlike behaviour - gimme more!
I did find the 3rd and 4th paragraph dragged me out of the scene, though. We already know that there is something unusual about the child and the watcher, so this is information that the reader doesn't need right now. Plus you mention the mystics in the 6th paragraph, so this makes it a bit repetitive. Hook 'em and keep 'em wondering a bit longer. I'd suggest ending the 2nd paragraph with "I want to believe that this is Seren, the one I have been looking for." And then delete the 3rd and 4th paragraphs. As usual, this is your story and you can ignore this advice if it doesn't fit.
In some cases, you've misused apostrophes to show a plural rather than a possesive. For example, "Middler’s are spirits" should be "Middlers are spirits", unless it's a "middler's something". Same with "Two-year old human’s babble".
Hope this helps. Did I mention that I love those crystal eyes?
