The Serenians claim that the nutrient nodules have the power to store the memories of their dead. They harvest these nodules, which they call "memory globes", and store them within the Chamber as they are "filled". A spiritual sisterhood, whose members call themselves the Protectors, is dedicated to this task, and to the care of the Memory Chamber.
The ability of the Memory Chamber to store memories depends on the root system being in contact with a "lifestone", which is kept in a ceremonial Root Chamber. The lifestone is a rare mineral of unknown properties found in the southern hills of Serenia, and probably serves the plant as an essential nutrient. If contact with a lifestone is broken, the fungus gradually loses its ability to remove and store memories. Ultimately the plant will die.
The sons of Atrus, Sirrus and Achenar, studied Serenian culture in their youth, and discovered a means by which a Memory Chamber could be used to extract memories from a living body.
