There won't be ogres and trolls, so these aren't veterans))
And as I understand from the first post, they're talking about those who have played from Heroes 1 to Heroes 5, so veterans can only be from four factions (not all creatures from the factions, but many))) from the human, elven, barbarian, and warlock factions. And some neutral creatures, like genies)). The rest are NOT VETERANS)))
I don't remember mummies in the first game, but they are in the others (and in the 5th game) as neutral creatures (in the 2nd game, they are with the Necropolis).
Champions and riders too)).
