I agree that the moral compass of fey beings in general is entirely different from other humanoids (a blue/orange axis instead of the black/white) - their moral framework is so utterly alien that "good" or "bad" cannot really be applied.
But (at least in the 5E monster manual) pixies in particular are described as mischievous, but not in a malicious way, their pranks are described as harmless (and I guess the MM uses the human definition of harmless, not a fey one 😄). The description makes them appear as benevolent, while still being little pranksters.
Another possibility could be to simply state that they can be mischievous in the lore check - and leave the definition of that up to the interpretation of the player.
Sorry, I should have made more clear that I was only talking about the lore check part - not about this particular pixie's personality.
While they have typical behaviours that comes with being fey they're still intelligent beings with individuality yes? So this one being "unpleasant" isn't that much of a stretch imo. As for the appearance, it did feel unfinished and unpolished but that makes sense as it didn't really seem like this was the release candidate build.
I think so, too - of course this pixie can be rude, she's an individual with her own personality.
The parts of this scene that bothered me were the lore check description, because it's quite different to the 5E description, and the unfinished looking model.
