This Glyph seems to have been left out of the list offered by the Inscription trainer (or at least, the one on the airship on GMI). Can we add it to his list please?
Then I apologize! Guess we can remove this thread :P
After doing a search (which I should have done first, I guess *facepalm*), I concur, it's supposed to. Problem is, Minor Inscription Research is bugging out for me. Should I continue, or post it in the bug section?
EDIT: Kretol worked his magic, GoS was added to the orc inscriptionist's buy-list on the airship at GMI, for those who want the glyph.
