Return of the King
Kyrie is the daughter of a very powerful man. She was given the necessary training that all nobles are given to survive in the byzantine strata of noble interactions, as well as combat training to give her a chance with assassins and vendettas. She is also a massively powerful Primaris Psyker. Sent on the dreaded Black Ship, she returned a potent sanctioned imperial Psyker. She was performing her duties serving a ranking member of the Ordo Hereticus when she and the inquisitor were kidnapped by the a group of rogue assassins. What little is known about why she was kidnapped and how she was able to escape seems to be linked with Xander Hastur and Severus Locke-Blackthorne.
At the events at the Aguisa Wayfarer Station, Kyrie is reunited with her father Martin on board the Divine Light, flagship of Lord Admiral Aleksandr Blackthorne.
