The Nomads were not included because all options involving using "native Heroes" units and redrawn creatures were immediately rejected. All monsters in the city should, in theory, be drawn from scratch. Mummies were initially planned to be used in the oldest version, but they were redrawn. Later, this idea was rejected.
Mixing these creatures with the Bastion's troops without a morale penalty is, in my opinion, an interesting idea, but it can only be decided through a general vote.
Do camels and overseers deviate from the overall graphical concept of the game or the overall graphical concept of the city?
P.S.
"Are you gangsters? No, we're Russian" (from the movie "Brother 2"). Although... Considering the development speed, it might be time to think about changing the nationality.
