tracking energy signatures

Normally, I would have tracked Molly down with a fairly simple piece of thaumaturgy I’d done a thousand times. After her unplanned vacation to Arctis Tor, in Faerie, I had always been sure to keep a fairly recent lock of her hair handy. And more recently, I’d found I could get a fix on all the energy patterns she used to make her first few independent magical tools—like the hair, they were something specific and unique to her and her alone. A signature. I could be pretty sure to find her when I needed to do so. Hell, for that matter, I’d spent so much time around her that she had become almost like family. I could generally tell by pure intuition when she was nearby, as long as she wasn’t actively trying to hide herself.
