This is where it gets a bit grey. Toun is manufacturing imitations of souls; the bare minimum for these things to operate autonomously. They don't interact with the primordial pool at all. When they die, the power just seeps back to Toun, no disturbance to the balance.

The trick is that the body of a white giant is such that this little control unit could be shunted out by a real soul. The serial number would be a stripped back husk of a real soul's name, and that Reathos could see it at all would be an unplanned feature.

For the sake of fun Reathos (and his followers in the Orders) will be able to see the serial numbers. It's definitly going to cause a lot of confusion.
