Who is Kristina Nilsson from The Settlers and what is their importance?

Kristina's faith in God is an important part of her life, and she struggles to understand His will..... to do what is right. She is a loyal friend and protective mother. She is also a hard worker, who realizes the toll that work has taken on her body. Kristina's greatest wish is to live long enough to see her children grown.
