A short summary of the content of the mod:
The mod improves most heros, similar to the dom2 Version  and enables a couple of additional heros, which are in the game, but seem to be disabled(bug?). 

In addition it also adds new multiheroes(heroes that can show up more than once) for a lot of nations. Most of them are fairly generic high mage type heroes, but all of them should be useful and thematic.
Almost all nations have a Multihero with the mod and every nation has at least 2.

Those newly created heroes are in a separate part of the .dm file, so you can easily remove those if you don´t like my creations.

There is also an updated blackheroview map, so you can check out the heroes easily, although you can´t easily see what nation/age they appear in. in addition I made pretty heavy usage of the custommagic command to have different multiheroes, so if you encounter any hero in the heroviewmap or ingame that seems to be overpowered, it may be a statistical outlier. 

Here is a hopefully complete list of Heros in the game. Heroes, which I added/enabled in the mod are marked as new, heroes where I´m not sure are marked with (not sure). Enjoy and please point out any errors:

As always any feedback is welcome, especially pointing out thematic flaws, or buggy behaviour. 

Stuff left to do:
1)New sprites for the new heroes, right now they still use the sprites from their templates. Although all of those are fitting, some distinction to normal units would be nice. Any help with drawing sprites would be greatly appreciated. I really want the artwork to be consistent with illwinters and I fear my drawing skills aren´t good enough.

Thanks to Sombre for some excellent hero graphics.

2) More heroes: If you have an idea for a hero, or already created a nice thematic one, post him and I will include him in the mod.

Credits for some ideas, which I used go to: 
1)Nerfix for the polypal mother hero idea.
2)Taqwus for the new atlantian multihero idea. 
3)Zepath for general ideas regarding king/angel heroes.
4)Endoperez for the High Seraphine Hero
5)Quantum mechani for the smoulderghost hero

Extra special credits for Jurri, who gave tons of useful feedback and had the flamecorpse hero idea.

Thanks to all the people who made suggestions in this thread even if I couldn´t implement them.
