Remembrance tank
From Tardis Wiki, the free Doctor Who reference
Remembrance Tanks allowed the Remote on Anathema to reproduce. A quantity of biomass would be placed within the remembrance tank, and a headset would be attached. Various citizens would come and literally 'remember' the person into existence. How a person would be 'remembered' depended on the impressions that the person imparted to the society. (EDA: Interference: Book One)
Faction Paradox used Gallifreyan biomass to remember Greyjan the Sane into existence. (EDA: The Ancestor Cell)
