Ice and Fire

You know, I was about to give up, but something kept me going, so I continued playing (as the hero). I'm approaching the 3rd Dwarf Castle. But still, I don't really understand how to defeat the AI hero with his 200 dragons (which are immune to fire magic). I read Rembo's rant on page 10, but it's not very clear (of course, not everyone can express their thoughts clearly). Moreover, his phrases like "placed neutral creatures" suggest that he's using the console. Anyway, I'll keep thinking about it. Still, "respect and kudos" to the author.
