NHF – new heroes for Heroes V 3.1.

Necromancer heroes from the campaigns in Heroes of Might and Magic VII. There are some memorable characters there. Zenda, Lyudmila, etc. It's unclear why they haven't been included in the project yet. However, I'm still using version 0.85 because of Roman's models. I can provide the icons; I use them myself.

I didn't understand the part about fan-made campaigns. Could I suggest Varens from the Unicorn Empire?
