Annika Olander is one of the protaginists of the Pyrrhin War.
Being both mother and grandmother-less, Annika spent a lot of her time as a child preparing food and tending for animals. Her father was a rather powerful viking, and she had to provide for them. Before long, her sister was brought home after one of her father's escapades, and she had someone to teach her trade.
Once Sina got old enough, Annika learned to fight. Much like many brave women of the Viking Age, she followed her father on his ship and watched how he fought, learning to fight herself.
Annika is very rough and tough. After a few heated battles, she's become jaded to the fact someone's life could be placed into her hands, and finds it intriguing to have such power.
