Dungeon

By the way, someone mentioned replacing the illithids with other creatures; there are plenty of options. For example, the Orog (underground, gray orcs – the most intelligent and good strategists, knowledgeable about the tactics of different races) from Forgotten Realms, they also live underground...

Well, still, it doesn't quite fit to have orcs who do everything directly (Barbarians) and dark elves, who will cause trouble before engaging in melee combat 8). Therefore, I think the illithids should stay, but instead of making them humans, they should be some kind of half-elves, but they should resemble drow in description. And since we won't have spiders, we need to remove the spider-like features and replace them with Shadowlords from Heroes 5, or replace them with illithids, and for the 5th-level unit, use lizard riders or hydras. And another important omission is the lack of dragons, which would be like an embodiment of the goddess or her servants. And there are no ordinary representatives of the race, such as minotaurs, but their ability for constant morale was given to kobolds, and honestly, from the dark elf race, some kind of academy from Heroes 5 appears.
kobold – why not a gremlin?
drow, why not a rajaka, although illithids could take their place due to their appearance, and it's also very strange that mind flayers live in the Dungeon; I think it's better to make them neutral, or followers of Shalassa, i.e., send them to the sea elves, or even to the nagas
