So yes! SKYSHIPS & SUMMONS got the following updates:

– I added a new paragraph to the ADVANCED RULES pamphlets that described a specific system of magic and magical elements players and GM could use in their S&S campaign. 

– I tweaked the sample starting jobs in the Game Masters Pamphlet to better match this sample magic system (Breath Mage instead of Blast mage, Scale Mage instead of Enchanter).

I'd thought for a while that the magic system in SKYSHIPS & SUMMONS was a bit vague. Hopefully this'll give players more to work with!
