Spoilers
Remember that Ardal from 100 years ago that couldn't even make it to the dragon because her carriage tipped over into the water (river)? Lefie is the soul of that Ardal - I don't remember the exact details but it had something to do with the river being connected to Simeon who was able to identify the soul and return her fate by taking her soul back from the modern world.

Can someone give me some spoilers on what’s the deal with Lefie? Was she being controlled by a divine being during the interrogation?
