Would that be "monkey truth"?
In this case, yes. If we're discussing what is or isn't monkeytruth, I reckon it's worth quoting from Temple Zero:
What is monkey truth?
'Monkey truth' is a particular aesthetic which recognizes the world's inherently fictional nature. Though the 'lore' has often been treated as if it were the record of some actually existing universe being recorded by these texts and images, a 'monkey truth' creation will above all attempt to present a world which is profoundly beautiful and magical. In such an aesthetic, internal consistency takes a backseat to marvel, which is far more important.
A monkey truth creation therefore is one which is successful in achieving the sense of an alien and exotic universe, avoiding standard fantasy genre conventions to achieve an overall sense of alterity, while still containing a successful narrative.
The term itself is at least a decade old, though it became a commonplace descriptor after writer and game developer Michael Kirkbride applied it to al Bede's "Orc Creation Myth". It has been summarized to mean "a story so good it should have been included in the game."
And my own thoughts: "Monkey Truth" is in this community often a stamp of high approval. It is probably a little presumptuous to label one's own work as monkeytruth, but there are plenty of clever people round here who pull it off all the time. Monkeytruth should be firmly grounded in TES lore, but is usually set on expanding or elaborating upon that which already exists, and so doesn't always need to be rigidly accurate (though it often is). Most importantly of all, monkey truth should reward a reader with an eager mind. It should be fun to read, and sometimes interesting to puzzle over (but not awkwardly puzzling). I think the Editorial Initiative have a thing on what monkeytruth is.
It is a truth. From monkeys. For monkeys.
You could also put it that way.
