Terry has ideas beyond that, but we'll see closer to the time how the Muse strikes him!
Terry is filled with wonderful ideas, maybe too many ideas. He gets overwhelmed and then doesn't write any of them down for the rest of us. Of course, he occasionally gets sick and then there's that annoying need to earn money at his real job.
As others have said, canon basically means Terry wrote it, likes it, or at least doesn't find it too out of sync with his vision. I remember an older discussion (probably on the silent tower mailing list) where Terry (after much prompting) separated things into a few more categories like:
- High Canon: He wrote it (but there still may be things he's changed his mind about a few decades later).
- Low Canon: Someone else wrote it and he likes it (or at least had already woven it into his vision years ago).
- Almost Canon: It's different enough that he doesn't want to fully support it (but you'll find references in the atlases).
- Not Canon: It's doesn't fit his vision or it's just a generic adventure (don't expect to see these mentioned anywhere).
The discussion wasn't that well organized in labeling or even in one giant listing, but over time various people asked about different modules and got responses. The tradition of Rolemaster is that the GM is always free to use or not use anything for a particular campaign. So if you've bought some module and like it, go ahead and use it.
A more practical use of the canon list is for ranking your future purchases. If it's canon, go ahead and buy (at any reasonable price), you'll probably like it. If it's not, don't say you weren't warned if you buy it and are disappointed. On the other hand, the generic adventure modules can be useful. And even the non-canon setting modules can be good. For example "Curse of Kabis" is a good RPG module, but just doesn't fit on Kulthea very well. So if it's a good price I'd still buy them all (and have).
If you get a chance at the Shadow World novels, Stormriders (originally by Roxanne Longstreet, but republished under the house pseudonym of Ian Hammell) is the only one you should consider. It's not canon, but it falls in the "at least it feel like it belongs" category. The one about clocks and swords is an OK story it just doesn't have anything related to Kulthea in it. The other two use Kulthean places and characters in extremely non-canon ways.
