Sounds fine to me.
As for the Grand High Torch, if you've got an idea, I'm open to it. The fluff made me think that the majority of people in the Magedom don't actually know if the Desert Ghosts are real (sort of like bogeymen) due to being a "secret order", but that threat of being burnt at the pyre was very real.
Originally, though, my idea was that Serafina had joined the Magedom's forces (possibly the Desert Ghosts, to make organizing our characters easier) but that she sort of made Grand High Torch up as a title for herself that she hopes to make real some day.
