I am looking for maps for Heroes III.

A long time ago, I played this map with my brother, and we both enjoyed it. I remember that the allies (the factions we played as) started in roughly the same place on the map, but one was on the surface and the other in the dungeon. Even without any modifications, the map was full of various events and decorative elements (like a huge skull, hourglasses) that couldn't be interacted with. Another feature was the presence of a large number of small islands - locations - in the dungeon, each with its own monsters and mini-story (for example, a fiery land and black dragons guarding a fiery sphere), which could be accessed using portals.
The main feature was that the Elves started in the dungeon.
And, something I haven't encountered in other versions of this map, was a clearly defined antagonist on a separate island, playing as Inferno (either pink or purple) with a huge army.
Please help me find it.:smile45:
