I assume practically everyone that has DMed D&D, even those who think the DM who said no to the Odin request "missed an opportunity", have a line they would not cross. An extreme example of course would be something like the player that says they call up their buddy an ancient dragon who just happens to be invincible and immune to all spells to destroy the enemy city.
Yes. I think I posted the same point upthread, though I didn't use the phrase "good faith".I think we have to assume a certain amount of good faith on the part of the player, right?
The real issue here seems to be fictional position. Under what circumstances does the players' fictional position include that their PC is friends with an ancient dragon? The default assumption of FRPGing is that they're not, unless this has been expressly established in play or via some distinct mechanic.
Straight away that distinguishes it from the Odin example - because the default assumption for a cleric of a god is that they are in some sort of communion with or relationship with their deity.
