I am looking for maps for Heroes III.

Hello, I'm looking for an XL map. - It should be very similar to Total War, but without water. - Cities should be located in the corners, and each should have its own faction; it shouldn't be possible to have identical factions (for 8 players). - The closer to the center, the stronger the monsters become. - It should have a dungeon where archangels, archdemons, etc., can be found. I remember it being around 20 years ago, but then it disappeared.
