I was impressed by the strength of the guard posts; I could only deal with them using dark magic. However, towards the end of the game, I was surprised to find that the opponent ignored them, using "astral gates" instead. This last circumstance negates all the author's efforts to improve the map...
Well, not entirely "negates," because you can't cross mountains using Astral Gates, so the teleporters that transport you from blue and red to yellow and green and vice versa without fighting the guard posts that protect them cannot be bypassed.
