Background

After a century of war, Dawnline's dead outnumbered its cemeteries. The Memorial Spire rose in their place: a vast vertical mausoleum, built ever higher as each floor filled, until it became a gothic monument to loss. From its memory and grief came Ossuary, a stoic archivist who remembers every name, battle and death within the Spire.

Ossuary gathers mementos from the fallen, etching their names into its endless bone arm and tending their memory like a garden.
