From Warhammer - The Old World - Lexicanum
Bertha knows all the Prayers of Sigmar and is favoured above all other sisters in the eyes of Sigmar. [1a]
Weapons and Equipment
|The pure blood of the Unberogens runs in Bertha’s veins, as evinced by her long golden plaits and fierce blue eyes, which can freeze a Goblin at twenty paces with an icy glare. Even her voice commands authority, turning strong, hairy-thewed men into trembling wretches. The Sisters look up to Bertha as an example of holy womanhood. She rose rapidly through the ranks of the Sisterhood, and on her deathbed the revered Matriarch Cassandra named Bertha her successor, new High Matriarch, and Abedissa of Sigmar’s Rock.
