Enemy in the Fort

The red-haired boy begins conversing with Ronja, boldly claiming he knows who she is. When Ronja inquires about who he is and how he got on the split side of the castle, the boy introduces himself as Birk Borkason. He reveals that he and his parents as well as his father's twelve robbers, the Borkas Bandits, moved in the night before and it is now Borkas' Keep.
