I am looking for maps for Heroes III.

Hello, heroes! Please help me find a map. XL/ At the beginning of the game, all playable factions have two castles each, one of which is fully built and contains a Grail and a hero with a large army and an artifact like the Alliance of Angels, and there is also a Horn of Plenty. This castle, along with all its wealth, is locked behind a fort, which requires collecting 300 units of each resource to release a strong hero. The second castle is a normal one, and you start the game from it until you free the hero with the army and the Alliance. I've been looking for this map for a long time, and if you help me, I will be very grateful.
