Remembrance tank
From Tardis Wiki, the free Doctor Who reference
The Remembrance Tanks allowed The Remote on Anathema to reproduce.
A quantity of bio-mass was placed within the remembrance tank, and a headset attached, various citizens would come and literally 'remember' the person into existance.
Therefore it was the impressions that a person imparted to the society that would ensure how they were 'remembered'. (EDA: Interference: Book One)
Greyjan the Sane was also remembered into existance using Gallifreyan biomass by the Faction Paradox. (EDA: The Ancestor Cell)
