Posts from RTF is a global modification that replaces all towns in the game.

We didn't want to make a thunderbird because of the presence of simurghs and coatls on the phoenix model; I want to make Rukh birds neutral. By the way, there's a Rukh head model from the sixth game in one Polish mod.

I'm working on repainting and refining the models; all the finished creatures are already balanced, except for the mages – I simply increased their difficulty and experience, as well as the power of all their spells, mana, and initiative.

If any interesting-looking mages appear, send me a screenshot or just describe them; I'm curious about what canonical characters exist in the free cities.

I should try this too... SRD intrigued me.

Okay, agreed. Basically, all the enemies you encounter are recorded in a bestiary, and you can always view them, play their animations, etc. Also, the lore is interestingly revealed in the books you find during the game. By the way, the game is mostly populated with units from Dark Messiah, Heroes 5, and Heroes 6, and as I understand it, the developers didn't bother creating new models but simply transferred them to Might & Magic X.
As for what's new, they interestingly showcased the Elves: the female elves, as I understand, have completely new models, while the male elves are a recolored and slightly edited model of Raileigh from Heroes 6.

I started playing yesterday, but the save menu glitched out.
