Which race would you add to Heroes?

Thank you, I'm trying. I just WANT new factions. The ones available aren't enough for me. And Warlocks – I've been familiar with them since the first Heroes game.

Yes, there are very few factions. There were nine in the third game, and I would have liked even more.

I would also really like it if, in addition to the overworld and underworld, they introduced a sky world, and created a castle and a race for the inhabitants of the sky. But I'll be waiting for that in the next "Heroes" game.
