I always knew those shifty Fae were up to something!!! Did you notice with Gnobrin's interview that the arches are good for as long as you own your home (paraphrased). So does this mean everytime you change your housing you need to buy a new arch? Filthy Fae what a dirty trick.
PS
I don't think so but when reading the interview the loop-hole in the wording jumped out at me as a great conspiracy theory to start:)))
