I'm not sure I can promise an *explanation* for Erem just yet... but some deepening mysteries and new clues, absolutely. (I mean, the basic answer is "A wizard did it," but the question of HOW a wizard did it is interesting to me.
I am glad you love the science wizards. I love them too. *g* (There's some architectural/geomantic wizardry in what the Aezin wizards do as well... )
