22 years later... Hopefully not too necro-posting...
Hi, this is the Ian the post mentions. MAG did indeed vanish. The setting has somewhat moved on (it is, after all, my own house game setting) - no longer called Aldor (Blizzard took that name), but since the name was originally lifted from the line of Rohirrim kings from Lord of the Rings, I'm not concerned.
Will it get published? Maybe. It is to the constant amusement of my wife as to how many times I've redeveloped chunks of it. There's a lot of material on lots of scribbled pages - even some spreadsheets. Just not in any order that would make sense to anyone outside of my head so much.
