You should be able to invite villagers to join your party and fight with you. In your party you could have 2 villagers, 2 magnus or 1 villager and 1 magnus. You should also be able to gift villagers armor, clothing and accessories and they would wear what you gift them. Rune Factory is a great example of a game does this.

I would like to be able to add villagers to my party, especially the one that i choose to marry.
Meh, imho Magnus > Peoples. To each their own.
I just thought that it would be fun to have the option to be able to have the person that marry or your child fight/adventure with you.
