Firstly, the attractive force, or whatever it is, is clearly powerful enough to attract light; hence why Myxidia men are completely colorless. At that level of attraction, suction, or whatever, the difference in inertia between a bunch of air and a rock are pretty insignificant--both are basically 0.

Now for your idea: That Myxidia is a wormhole into vacuum.

Air is not attracted to vacuum in any way; get this into your mind right now. There is no special force that causes air in a space station to be sucked into space if there is a hole in the hull. In theory, all the air could happen to remain inside the space station without any aid from technology. Why doesn't it? Enter entropy.
Imagine that, instead of a space station or a Pit of Magic, you have two hermetically sealed rooms connected by a fairly large, airtight door. One room is full of air, one has vacuum in it. In the room full of air, air molecules are constantly moving at a rate dependent on the temperature of the room. Many--about half, in fact--of the air molecules near a wall are moving straight for it; when they hit the wall, they simply bounce off and remain in the room rather than going through the walls. The same goes for air molecules near the door. Meanwhile, deeper in, some air molecules are deflected away from the area by the wall or the door by molecules bouncing off of the wall or door.
Now imagine that the door is opened. Remember those air molecules near the door? The ones that didn't leave the room because they struck and rebounded off of the door? They head through the open doorway and into the second room. The air molecules do not rebound, and hence do not bounce other air molecules heading that way away from the now-empty doorway; the molecules are able to head for the doorway, and then into the second room. Soon enough--and it is very soon, because air molecules move pretty fast--about half of the air molecules have moved into the second room (assuming that the rooms are of approximately equal size, of course) and the air pressure is equal on both sides of the door.
Now for the point of this exercise: The force which draws air into a vacuum is exactly the same as that which causes it to strike the edges of a "tunnel". When air is drawn into a wormhole, it will not be compressed to avoid hitting the edges of the tunnel; it will collide with other air molecules and expand until it fills the space it can fill. The force drawing the air into the wormhole is exactly the same force. Air will not rush into the vacuum and carefully avoid hitting the walls of the tunnel, any more than it would have entered the second room and avoided hitting the walls in the example I gave above.

Any questions?
