NHF – new heroes for Heroes V 3.1.

2) Have you ever watched the 3rd and 4th parts of the movie "Fantagiro - The Cave of the Golden Rose"? No? Watch it – it's an awesome movie with great characters!)))
So, I suggest creating campaign maps based on the plot of this movie, but with some author's edits and small fan jokes.
The heroes would be: Tarabas (the ultimate mage, evil, etc.), Xelesia (his mother, an evil Sorceress, lol), Darken (his father, an all-powerful demon-mage in a human body ((in the movie, he's a demon, but in a human body, and in reality, he's a human mage)).
I came up with the following Special Abilities (SA) for the heroes:
Tarabas: for each level, +2 to Knowledge and Magic, SA Lord of Evil + Arcane Mastery – all "evil" races join him. (an example of this is Markel, but with undead, and here, all evil races), and development along a mixed Warlock and Mage wheel.
Xelesia: for each level, +2 to Knowledge and +1 to Defense, SA (Mystic), development as a Mage.
Darken: for each level, Magic and Knowledge +2, SA (the same as Tarabas, but it will be Arcane Mastery and summoning 3 Archdemons on the battlefield (like Arantir summons his avatar with stats, but here, it's demons...), and the skill – for every 2 levels of the hero, the attack and defense of Demons, Archdemons, and Demon Lords increase by +2).
Even if it's not possible to create maps, help me create at least the heroes (if they are too overpowered, I'll keep them for myself, and for the rest, we'll make them balanced).
What do you think? What are your ideas?
