I don't know whther this is supposed to work this way, but I tried to teleport my commander into a province that had a Dome of solid air. He got repelled by it, and I got the message that the dome prevented a hostile spell. I thought that only spells from other nations will be stopped, not my own? I shudder to think what would have happened if I had the Dome of flaming death or Dome of corruption instead. In any case, if it succeeded it would have shattered the dome and wasted me 20 gems. If it's working as intended, I guess it's better to know sooner than later.
Btw, I can just imagine him getting stopped by an invisible force and then flung back in Looney tunes style...
