“Alternative League” is a mod that replaces the Dungeon faction.

And I immediately understand why. It's a result of an old fix for a UI bug. I've already figured out how to fix it and I've already done it. Now you can convert creatures into undead. It's a workaround, but it seems adequate.

Today, instead of development, I conducted balance tests. Overall, everything is very good, but Orcs are overpowered.
