- "I speak for Sang'ket, first of the Bloodraven Order. Live giver, and life taker. Daughter of the Sea."
- — Klaus Fischer
The Bloodraven Order is an ancient order centred around protection and the use of blood. Sang'ket, being the first member of the Order wielded a shield crafted in the city of Thule which became known as the Roar of Sang'ket.
Emperor Frederick Barbarossa had his four highest Royal Guards be members of the four Raven Orders, with their notable weapons being attributed to the order as well. The member of the Bloodraven order that was a Royal Guard wielded the sword known as "Bloodthirst" that was said to boil the blood of the unworthy along with being a sister to the Red Talon that was lost during the Crusades.
Klaus Fischer utilising stolen research and technology from Peter Straub created modified Überschanlle that require different resonance frequencies charge, with the Bloodraven requiring Pests to charge it. The Bloodraven charged Überschanlle then is used to create parts for the Tesla Gun that change how the gun functions. Klaus hid the Überschanlle and research away prior to his capturing by Doctor Straub.
After his death Klaus became the new Rook which allowed him to make Raven squad into members of the Raven Lords.
The available research from the Bloodraven tree mainly provides support abilities, focusing more on the cooperative aspect, team assist roles and joint annihilation, as the shown by the Team upgrades mods available for all four Special Abilities, which provides Geistchild, damage bonus, Health or enhanced revive tools to any nearby teammates.
