There are similar mods online. They feature Orson as a dead peasant, etc.
But I think having heroes with the "Cree" skill is a no-go.

It's possible. I need to think about it.
A Fallen Knight will immediately give +5 to Dark Magic (Yorgen gives +6 to Dark Magic and enhanced armor (level 7 and 6)). Since I'm adding a skill point to everyone, the "Fallen Knight" can now be given at the start. But the special ability itself should be based on education (and Sergio has such a special ability).
Then Sergio needs to be given a different special ability.
