And the runes need to say something to be read. And they did!
But the
method of establishment is what is under scrutiny here! In the cleric example the existence was handwaved. I thought the point of the sentence you quoted here was to point out that this handwaving was inaproperiate
in this context.
You get irritated when I post that people seem to confuse fiction and reality, but this is exactly an example of that. In the fiction, a cleric can only be found and persuaded if they can exist.
But at the table, a player can trivially declare "I am going to find a cleric to persuade" without any cleric having yet been authored. And if the GM replies "OK, there are clerics at the temple but it will be DC 18 to persuade one of them to help you", that is completely bog standard. It is unremarkable that the player's action declaration prompts the GM to author some clerics.
You appear to be confusing if people are talking about fiction or reality. From my reading it appeared obvious that
@Crimson Longinus talked about existence from an in-fiction perspective.
More generally, it is utterly commonplace, in RPGing, for fiction to be authored in response to action declarations, although in the fiction that existence of those fictional elements predates the action declaration and is something on which the success of the declared action depends. (Eg a person can't find a cleric if no cleric exists.) The difference between the runes case and the cleric case I described in the previous paragraph is simply that in the runes case there is a mechanical procedure that the player contributes to whereas in the cleric case the GM is responding to a player prompt.
Neither is more or less "meta" or more or less "dissociated". But one is more player-driven than the other.
Here you get to what I think is your good point. I hope it didn't get too muddled by the above.
I have two counter point to this:
The first is that I think there is a stronger
incentive to engage in this kind of dissociated meta behavior if you sit in the driver's seat than the passager seat.
The other is that while a prompt to author
might be as overt, meta and dissociated as actually authoring it yourself, it also
can be devoid of these properties (while authoring seemingly cannot)
A clear example is that a
character can decide to go check out the temple. A
player can hence declare that their character go check out the temple without any dissociation. This declaration however
might prompt GM authorship of temple details. As the player don't even know if authorship happened as part of this declaration, that cannot change their experienced absence of dissociation.
