HoMM VII Haven Units – Haven faction units from the seventh installment of Heroes of Might and Magic.

Yes, something like that. FrozenSol didn't really show off these things on the forum; we discussed it in private messages.
At the time we were discussing it (a couple of months ago), everything was about 90% complete; all that was left was to render the texture in Substance Painter. What happened next, whether FrozenSol abandoned the manticore or not, I honestly don't know.

I don't understand Footman's politics with modding. He did all that work, just to post pictures on the forum, but he already said that he doesn't want to release it to the public. So why is he posting on the forum "publicly"? I think that this is very close to boasting himself. When I asked him about the technique of how he imports Heroes 6 models correctly, if there is another way than the method that I use with Blender, which took me about 12 days/1 model. And he replied that it is "secret" .......When I showed him what I have accomplished, he wanted to make a deal that if I fix his Heroes 6 crossbowman animations (all of them), he will give me 1 model (that's almost the same as making another Heroes 6 model for me myself). I don't really get that whole approach. Why is he doing all of that? But whatever, I will make it myself; it will just be even longer than I expected. First, I will import some Heroes 7 models and then sculpt my own Pit Lord with some Heroes 6 units.
