Coming to their village, the wizard Raevil took three women as his apprentices: Bera, Groa and an unnamed woman. Raevil taught them his art. The more they knew, the more they wanted. It corrupted them, turning them against each other. Groa killed the unnamed woman. Bera and Groa stayed rivals for a very long time, until they were killed Rikard and Kadlin. Kadlin was later revealed to be the daughter of the unnamed woman, who was killed by Groa.
After her death, Bera and Groa were revived by Kadlin to serve as her assistents, working together with Rikard to make the lands safer.
