Caeistia Mehrkuri

Caeistia Mehrkuri was the middle child of Castella Mehrkuri and Asterion Barro. She was the younger sister of Primarch Astraea Mehrkuri of Digeris and the older sister of Maxim Mehrkuri, who was killed in action during the Relay 314 Incident. Her husband, Stephanus Kindrax, was also killed in action during the Reaper War. The pair had no children together, a fact Caeistia mourned in later life.

Caeistia served her sister as an informal advisor during her rebellion against Desolas Arterius II. After Astraea's capture and subsequent execution at Desolas' hands, Caeistia continued to serve her family's ambitions by assisting her sister's widower, Antraxes Partinax, in his plot to claim the Aurelion Throne. For her loyalty and service, Antraxes promoted her to the position of Turian Councillor, replacing the exiled Janus Arterius who he had forcibly removed from power.

Despite her role in Antraxes' illegal administration, Fidellion chose to show mercy to Caeistia. He spared her life but stripped her of her rank and its privileges as punishment for her crimes, relegating her to a private person with no true standing in the hierarchy. While their relationship would always be somewhat frosty, Fidellion grew to value her counsel and would eventually foster a sense of professional respect for her.

Caeistia spent the rest of her life mentoring her nephew, Astraeus, who was her sister's only surviving child. She viewed Astraeus as the son she had never had and was fiercely devoted to him. She would live to see his inauguration as Primarch of Digeris, said to be the proudest moment of her life, before passing away peacefully in her sleep a few weeks later. She was interred within the Mehrkuri family tomb in the Apparitan Necropolis on Digeris, beside the body of her long-dead husband. From then on, Astraeus would forever refer to her as his Domina Matertera, or "Lady Aunt", out of love and respect for her.
