I am looking for maps for Heroes III.

Help me find a map. Size XL. We start in the upper left corner. The hero has, I think, only 1 or 2 units, I don't remember who. You can't recruit anyone in the castle. We fight all the time against one, two, or several units. Gradually, we conquer scrolls, artifacts, etc. Over time, neutral units join us one by one, and so on. The map features a Dungeon, and time doesn't play any role; we need to get somewhere. The map is very long and complex. I really need it; I've been looking for it for several years.
