This is of no help to the newcomers, but the old-comers have been saying for a couple of years now ( I have been one of them) that within Glorantha's "World Logic" myth is far more important than mere logic. Runes not atoms, Myths not theories... rivers run down his because once they did to satisfy an old story... gravity, what’s that?
What I mean, is, we gloranthaphiles have know for 4 decades that Chalana Arroy could not, would not let sleep out of her protective hands, ever. If a critter was slept by a CA it also was under her protection through the proxy initiate or Rune Master.. I can not even recall where i read that but I am sure I read it more than once, maybe in Greg Says from Issaries, possibly a zine, mag or one of the great Web Pages/digests or dailies from back in the day. But I assure you we fans (an Orlanthi all) knew that only CA would have sleep.
And if we didn’t , oh well, Home Rules, ya know? People let their Glorantha Vary even then.
Now this is a fault I hope is corrected in GaGoG, that is Ludo’s comment about, "Make it clear which spells are indeed cult secrets”. Having this in the rules will help especially those not soaked in Glorantha myth.
Again, I have just know that this one particular problematic spell we have seen discussed here really could not be a problem or Glorantha would have to radically different then is used to be. The Sun rises and sets (usually) in Glorantha, and communication is the Rune owned by Issaries and Sleep belongs to CA (now of course, I have been playing too long on the lozenge to say this will always be).
Me, I am still awaiting the full RQ Glorantha FRP game. We have a good start but there are two pieces I will need to buy adn have in my mitts to finally be able to say "I have the whole game" The Gods and the Game Master books. Again, apologies, this is not fair and this should have been covered by now, but without those books it is quite like RQ 2 without CoP, Troll Pak, Griffin Mountain, RQ Companion, WF and all the supplements that made RQ great.
I will note, and I think lordabdul might concur, there is a new movement of advancing Glorantha froward in the public conscious today, and it is the Jonstown Compendium crew of creators. I think we can be happy with our near finished game while we delve into Fan Goodness, no? The Chaosium crew have been doing mighty good work , I see no reason they will stop now and once the game is complete I think it will be easier to judge how well they did,
