Thank you for that answer! I asked several times already and it's the first time I get an answer. And it's one that makes sense on top of it! Meaning it's probable most people don't understand the concept either.
So, it's a translation incompetence issue, then. Because they could use other words instead, like "celestial" or "extraplanar" which don't have the same connotation and "genius" (which seems to derive from the name of a demon type) or "prodigy".
