Heroes of Might & Magic III: Horn of the Abyss

Since there will be new factions, dwellings for their monsters and storages are also needed, because in 6 out of 8 external dwellings give resources, and creatures are only in the Griffin Conservatory and the goose house, so I think it is reasonable to create external dwellings with creatures for the new factions!
-------------
Also, here is an idea to create (Name options) "Temple of Magic" / "Haven of Sorcery":
A battle with 1-4 Magic Dragons, 5-20 Wizards, and 2 stacks of 4-16 Genies each. The fight takes place on the Magic Plains (so the Genies cast on everyone:)). After victory, you receive 1 artifact (tomes of magic, spheres) and 4 scrolls with different spells of levels 1-5 (depending on the battle difficulty).
----------
Also, for example, you could make external dwellings for crystal/rust dragons:
Upon victory, they give 1-2 of the corresponding creatures and 16-32 of the corresponding resources (crystals/sulfur).
---------
"Ice Palace" (or something else...):
Battles with Azure Dragons — after victory, the hero receives an additional 10,000-40,000 experience (well, naturally, one should be proud of such a victory ;) ).

----------
Alright, I'll have more ideas, I'll write them down! ;)
