The Ghost-Weavers

Memory is a sacred Matter.

Core Concept

While the Arborians craft with life, genetics, and cultivation, the Thanatechs are a species of necromantic engineers who craft with death, decay, and memory itself. They do not see death as an end, but as a resource; the moment a being’s Eidos becomes a potent, harvestable fuel.

Physiology & Biology

They may be skeletal, ethereal, or symbiotic with decaying organisms. Their biology allows them to perceive and manipulate the “ectoplasmic residue” or “ghost-data” left behind by the recently deceased.

Psychology & Society (Faith / Fiction)

Core Faith: They believe that a powerful memory—especially one of grief, love, or trauma—is a tangible force that can be harvested, refined, and used to power their technology. Their society is structured around elaborate funerary rites, which are both acts of reverence and industrial-scale resource extraction.

Core Fiction: Their most revered figures are not warriors, but “Grief-smiths” who can forge the memory of a hero’s last stand into a sentient, haunted weapon, or weave a mother’s sorrow for her lost child into a protective ward.

Gameplay Hooks & Tensions

The Craft system for a Thanatech is unique and morally complex. To create their most powerful items, they require not just metal and stone, but specific Eidos fragments as catalysts: [Grief], [Betrayal], [Lasting_Love]. This might lead to quests where the player must provoke specific emotional events in others simply to harvest the resulting “ghost-fuel.”

Their relationship with the Arborians is one of profound ideological horror. The Arborians see life as sacred scripture to be cultivated; the Thanatechs see it as a container for the fuel that is only released when the container is broken.
