Founded three centuries ago during the Great Silt Fever. When the dead began to rise from the riverbeds due to a lingering necrotic miasma, a group of bereaved citizens realized simple burial was insufficient. They developed the Silvering Rites to bind souls to their rest. Over decades, this civilian militia evolved into a sanctified order of memento mori, eventually constructing the House of Passing to serve as a fortress against the restless. Their most defining moment was the Great Sealing of the 14th Flood, where they successfully suppressed an army of river-ghouls at the cost of half their membership.

The House of Passing is a sprawling complex of grey stone and iron built over the town's oldest catacombs. Its narrow windows are barred with silver, and the air inside is heavy with the scent of incense and damp earth.
