Alfhild (Alf and Alfhild)
When Alfhild was a young princess, the room she slept in was guarded by a lizard and a snake. These reptiles scared away suitors who were not brave. A Danish prince named Alf, who was also Geatish, came to Geatland and fought the animal guards and won. But Alfhild's mother told her to run away from Alf dressed as a man.  She did, and she became a woman fighter called a shield maiden.
