"In a way", not crystals are magic my phrasing tends to be on borderline but I know enough to make enough loopholes to make sure I'm not wrong about what I put up nowadays.

Still I suppose you could fault me if you wanted to pursue but honestly we would be getting off topic.

Answering the questions at hand:

Aincrad is floating because it is in space in manner of speaking below the clouds there is nothing and if physics are coded according to ours something can exist in space kind of like how the solar system doesn't have a floor and the planets are just floating in space

Elucidator - was probably called a "makken" usually has two meanings magic sword (mahou ken), or demon sword (akuma ken), excuse my romanji cause it sucks. Elucidator has no magic it is just such a powerful weapon in stats that it it was called a demonic drop > makken. English version probably just used magic sword or something (I've never seen the dub and I never will) so the misunderstanding stems from that.
