The Remembrance Society is a community organization of approximately 1,500 members dedicated to documenting and memorializing the lives of GLMZ residents who die without being remembered — the unclaimed dead, the undocumented, the people who fall through every system and leave no record that they existed. In a city where corporate databases define reality and the poor die without obituaries, the Remembrance Society insists on the radical act of noticing.

The Society's volunteers visit morgues, monitor missing persons reports, walk the streets of the deep Shelf and the Underworld, and document every death they can — recording names when names are known, descriptions when they aren't, circumstances when they can be determined, and the simple fact of a life ended when nothing else can be established. They maintain the Memorial Wall — a constantly updated digital and physical record in the Shelf that lists every documented death, and that has become a pilgrimage site for people seeking evidence that their lost loved ones were noticed by someone.

The Society also conducts memorial services — simple ceremonies marking the death of individuals who would otherwise have no funeral, no mourners, and no acknowledgment that they lived. These services are attended by whoever comes — sometimes family members who couldn't afford a funeral, sometimes strangers who believe nobody should die unmourned, sometimes nobody at all except the Society's officiants.
