My dark dwarves have music from Heroes 3, but it's been reworked for Heroes 6.

Added 3 minutes ago

I searched on a Polish website and found an interesting model that would be perfect for the "Chudishche." I think it's made from a cyclops?

The "Chudishche" is a cyclops with the head of a yeti, the arms of a Kappa, the horns of an Archdemon, and I think it has something on its chest and possibly on its back.

My dark dwarves have music from Heroes 3, but remixed for Heroes 6.

Remix :)
What are your ideas regarding the mages (style, units, etc.)?

Chimera mages are called crimson mages – perhaps this is their main color; the city probably shouldn’t fly, and it’s quite possible to create a combination of lizards, minotaurs, centaurs, and harpies.

They could also include gnolls.

if we leave the Nagas, then of course, Ashan! Elementals – the Zehirian reform, or simply, after the coming of the Messiah, the most combat-ready force were mages and demons, and they struck at the golems, so there was nowhere to produce them, and they returned to the Realm of Spirits.

We can make the Lizardmen part of the Beastmen faction, but they turned out to be the most powerful and gathered other Beastmen around them. The cowardly Gnolls joined immediately, as did the Rotworms and Harpies.

Sareth did free the demons, but they didn't conquer the world; instead, they became, let's say, "aggressive neighbors" to the other factions. With the arrival of the demons in Ashan, the cycles of eclipses ended, and the cycles of the Void began. In general, the demons became Ashan's second-biggest enemy, and the Order of the Void, led by Sandro, rose to a dominant position. I have no idea what the future holds for this. This information comes from Erwan's presentation on Ashan.

And then I had the following ideas: all the factions united against the demons and Sandro – the elves, most of the orcs, and the dark elves were destroyed; the dwarves turned to dark forces (to survive); the human kingdom declined; and in the world of spirits, all the dragon gods weakened Urgash (but didn't kill him, because there must be a balance between order and chaos), and all the demons (or almost all of them) disappeared. After that, the gods destroyed Sandro, and most of his army "died"; the rest escaped and joined the Black Skull orc clan. The mages scattered, some becoming elementalists, others followers of the Chimera. Meanwhile, new races arrive in Ashan...

interesting, but it could also be different: the demon army managed to conquer the land of mages first and destroy everything there, then the orcs from the islands of Paao began to gather their forces, the desert dwellers started to wage war (many gnolls are fleeing), and the orcs from the taiga joined the island orcs, but they will all be defeated and will cease to be a military power. the undead will be destroyed next, and the humans will organize a defense, and the elves will join them, and the dwarves will close their borders to outsiders. after the defeat of the elven fronts, the significantly weakened demon army destroys the main force of the humans, the angels betray the empire and go over to the side of darkness, and revive the cult of the void, and on the islands of shadows and the armies of evil invade the lands of the dark empire. the continuation can be thought of later.

Also, it’s interesting, but what happened to the dwarves? And the dark elves? And so on.

Okay, the main point is that half of the old factions were destroyed, and the other half is in decline, and new races are appearing.

By the way, what do you think of my idea about the Chimera mages? :D (or rather, your idea, reworked)

That's an interesting idea, and now let's continue. Angels invaded the dark empire and landed in Grimheim, but the north of the dark empire is populated by light elves, and they are fighting back against the angels. Enraged, the angels summon the forces of darkness and go mad; now they are servants of the Void, but the dark dwarves were preparing for the return of their former masters and are putting up a good fight. Further south, the dwarven army captures the settlements abandoned by the horde and sells their inhabitants into slavery. The orcs join the forces of evil, and the remaining forces of evil invade Grimheim. The dark elves attack the legions of demons from the flank, and some warlocks go to the mages of the Chimera's Lair, who live in Kartal on the Egin peninsula, and teach them dark magic (or organize a cult of the Chimera). After the destruction of the main forces of the dark elves, their remnants unite with the surviving mages and create a new army (Nexus and the fusion of elements, perhaps Arcania). In the east, there are no more orcs, and the slave traders begin to send ships to the islands of Pao and organize a pirate army.

Interesting :)
But what is meant by the "dark empire"?

the demons have been defeated, the griffin empire lies in ruins, the dwarves are weakened by an attack from the sea and are closing their borders, Irolan is weakened, Igg Shail has lost most of his army, the golem factories have been destroyed, and the necromancers have been annihilated.

the Dark Empire is the land of the dark dwarves in the north of Ranaan, waging war against the orcs and trading slaves with the free cities.
