I am looking for the word that refers to the set of rules/laws within a fictional universe which maintains the realism within the universe.
Eg. Within The Lord of the Rings it is established that magic, elves, trolls etc are all realistic within this fantasy universe as it is established early on in the story, however, were Frodo to suddenly pull out a mobile telephone and let Gandalf know he was on his way to Mt Doom it would be unrealistic within the universe.
Words that it is not:
- World building
I seen it for the first time in a forum I can no longer find. All synonyms of realism are not what the word is either. I believe it to be specific to rules/laws within fictional/alternate universes created that maintain the status quo of realism.
I apologise if this is unclear but cannot think of another way to explain it and simply hope someone reading this knows the word.
