Weird corner case rules question (Point of No Return)

[HamHamJ2 136]

So I was playing Point of No Return and drew Unexpected Ambush. If I had failed the test, the only enemy in play was a Gug back in the City of Gugs. To reach me, he would need to pass through Plain of the Ghouls, which he is not allowed to enter. What happens? Does he try to move as far as possible (assuming there were intermediate locations between the two)? Does he not move at all? Does he ignore the text on Plain of Ghouls and teleport to me?

Cannot is absolute and it explicitly says to move one location at a time so I feel confident in saying that the Gug doesn’t teleport to you (or reach you at all). I would think that the Gug moves as far as possible rather than not moving at all because you’d resolve as much of the effect as possible.

this also came up in our group and we decided that the enemy would move as far as possible and then stop just before the Plain of the Ghouls.  We were kind of sad, because it was an enemy with Victory 1 that we left behind and it would have actually been helpful if it could move to our location.
