Remembrance tank

Remembrance Tanks allowed the Remote on Anathema to reproduce. A quantity of biomass would be placed in the remembrance tank and a headset would be attached. Citizens would come and literally 'remember' the person into existence. How a person was 'remembered' depended on the impressions that the person had imparted to the society. (PROSE: Interference - Book One)

Faction Paradox used Gallifreyan biomass to remember Greyjan the Sane into existence. (PROSE: The Ancestor Cell)
