Frieda and Ragna, once hag servants to the primarch Naziith, had their destinies forever altered when they were bitten by the Werebear Thorbjorn. Transformed into werebears themselves, the sisters chose to serve Thorbjorn and his ally, Kairus the Brass of the Brass Tribe. They used their cunning arcane tricks and immense strength to shield the tribe from outsider intrusion, teaching the tribe members powerful defensive and offensive techniques.
As the Rift-Reavers attacked, Frieda and Ragna roared into battle, their werebear forms towering over their enemies. The sisters fought with a savage fury, their claws and fangs tearing through the ranks of the assassins. Their knowledge of arcane magic allowed them to cast powerful spells, creating illusions and barriers to protect their kin.
Despite their immense strength and magical prowess, Frieda and Ragna could not withstand the relentless onslaught of Karthus Wargrym and his Rift-Reavers. The warlord's devotion to Bhaal fueled his rage, making him nearly unstoppable. The sisters fought bravely, using every trick and spell at their disposal, but one by one, they fell to Karthus' brutal attacks. With their dying breaths, they cursed Karthus and swore vengeance for the fallen tribe.
