The largest map.

Hello everyone! Guys, could you suggest a really large map for Heroes 3? I would even say a huge map! I remember that a long time ago, one of my acquaintances used the Heroes 3 editor from the "Armageddon's Blade" version to install a map for me that was so large that I couldn't reach the other end in weeks of playing! There was no campaign in it, just a map for running around against the AI (it was probably already in the game file, you just had to activate it somehow). I would be very grateful if you could help me with this!
