The Soul Reader is an object enchanted by Darkstalker to show how much of a dragon's soul was good, and how much of it was evil. Darkstalker created it to show Fathom that Fathom didn't need to worry about Darkstalker's soul, as Fathom was, due to Darkstalker's use of Darkstalker's animus powers.
The Soul Reader looks like a telescope with an hourglass stuck to the top of it, with the hourglass containing white sand and black sand, which showed you the levels of good/evil in your soul. It displayed on one side black for good and white for evil. So the more black sand it contained, the better condition your soul was in.
The Soul Reader was created and used several times before it was forgotten in Fathom's room for over 2,000 years.
- The Soul Reader was created by Darkstalker about 2000 years ago.
- Darkstalker explained that the black sand was for good, because NightWings are black, and white sand is for evil, because IceWings are white.
- The soul reader has been used on Darkstalker, Fathom, and Clearsight, and Darkstalker said he had used it on Prince Arctic. Their souls were 75% good, 75% good, very good with a little bad, and "almost all bad", respectively. Clearsight was confused why she had some white sand, as she could never remember doing anything evil. This could be because she was interfering with the timeline.
- It is unknown if the Soul Reader will play an important role in any future Wings of Fire books.
- It is possible that, when Whiteout said (in Darkstalker: Legends) "That's all right, he's not going to snow for a while," and, "It's too late. The sand is falling," that she was calling the white sand in the hourglass the 'snow'. However, no further evidence indicates she knew about the properties of the hourglass.
- It is unknown if the Soul Reader is breakable as it is shown in Talons of Power that Anemone threw away the hourglass, believing it to be useless.
