your questions regarding the game rules (improving the interpretation).

There is an analysis of such a situation in the comments to the rules


It says there: The passage from the Tower's starting zone to the center is guarded by two control points – Golden Dragons and Sultan Efreet. The Blue player has the right to break through any guard he chooses. He can go out onto the sand and pass by the shifted dragons to attack the efreets. Also, Wings of Angel, Flight, or Dimension Door can be used to attack the efreets.
Goblins can be taken from an external dwelling without breaking through the control point.

Nothing needs to be changed in this rule; it should only be added that control can be used in this case only to avoid fighting one of the control points, while moving across free cells of the treasure zone before breaking through your own control point is prohibited.

In this picture, the control point - Efreets are also moved further back.
II.2.6.2. If the guard of the passage between zones is shifted into the neighboring zone, then passing into this zone is allowed to eliminate it.
Therefore, I believe that you can only walk along the empty cells of the treasure zone for two sand cells to the left of the efreets.
Using wings to fly over the Hive and Imp Nest on the sand to reach the Efreet control point is prohibited.
