Gud, if it blocks out light, would it also block out everything else? Kind of a sensory-deprivation area? (Also - air? would they start feeling like they were suffocating because they were?)

As I figured it there would be no light and sound from the outside would be greatly muffled and distorted, but you'd still get smell and wind albeit reduced. Also I was figuring one could only use dim illumination inside because every bit of light get absorbed and turned into heat.

OK yeah that would freak me right the heck out. I might start running in some random direction.

Cool, it sounds like I'm not totally off base in have a couple freak outs.

While driving to work, I just started thinking what it would mean to have something make an area invisible, realized that it would likely make this weird place where no light comes in, then thought maybe the first time it is used all the character reactions could be used to establish some stuff about the characters.

Thanks for letting me bounce stuff.

We're your bouncy castle of writing fun, Gud.

Gudanov, it wasn't invisible from the outside, but what you described reminds me of the scenes inside the stasis field in Haldeman's Forever War.

One magical device creates a dome that renders everything inside invisible from the outside. Conversely, if you are inside it, all light from the outside is blocked

That sounds a lot like what an actual invisibility field would be like. If, you know, they were able to create one on something larger than the nanoscale.

I try to sneak physics into the magic wherever I can. I need to establish limits to prevent lots of internal consistency problems.

Oh very cool Gud.
