Flungus

I have been listening to the audiobook version of Arcanum Unbounded recently and something stood out to me. The specific way that Lift uses the food she has eaten to facilitate her surgebinding is very similar to how sandmasters use the water in their own bodies to facilitate investiture on Taldain. This leads me to one of three conclusions,: 1) One of her parents were a worldhopper from Taldain and her unique surgebinding is a result of having parents from two different magic systems. 2) She herself is somehow a worldhopper from Taldain resulting in something similar (though I think this unlikely.) 3) Knowing that she went to the Nightcrawler to ask for a favour, is it possible that the Nightcrawler is a sliver (similar to the Stormfather for Honor) nor of cultivation as has been previously guessed but of Autonomy? Thoughts? Comments?
