I don't have a lot of the reference works, but am hoping to start
buying some soon-ish. Do any of them look into the Gloranthan future
whence KoS comes? Or even up as far as after many/most/all the gods
are gone/dead/unreachable/whatever, with regards to what happens with
magic? (it is really that latter that I'm curious about how it is
handled).
