You Can’t Get There from Here.
Barriers exist between Athas and other places. In the case of other planes of existence, the Gray impedes travel. In the case of other places in the Prime Material
Plane, the crystal sphere surrounding Athas is impenetrable. Consequently, travel via spelljamming is impossible, and planar travel is much more difficult.
When it comes to magical means of planar travel, the buffer formed by the Gray imposes some restrictions. Both wizard and priest spells that provide access to or contact with other planes, from astral spell to gate to planeshift, require an additional check to see if the energy of the spell cuts through the barrier formed by the Gray.
A priest reaching out to his patron element doesn’t need to make this check. Other characters modify the check by adding their level to the number rolled.
For example, if a 9th-level preserver casts contact other plane, he adds +9 to the check.
The same holds true for those trying to contact or reach Athas. The barrier formed by the Gray impedes travel in both directions.

Lost in the Gray
If a character tries to travel to or from Athas in a planar fashion, there’s a chance he’ll get lost in the Gray. In the Gray, lost characters get one chance each day to find their way back to where they started. In no case can they go forward! The check consists of rolling your Intelligence score or less on 1d100. If this check fails, not only does the character remain lost, but the life-sapping effects of the Gray begin to take a toll. The character permanently losses one Constitution point. If the character can’t find his way back and his Constitution score falls to 0, he is absorbed into the
Gray and dies. If he does return, lost Constitution points can only be restored by powerful magic.
