Odrun Fell

The Threadspire Archive is the premier independent cartographic house in Odrun Fell. It's operated under freelance surveyors, archivists, and wayfinders who update its living map collection through direct experience rather than secondhand accounts. The heart of the archive is its Living Loom, which is a magically suspended web of articulated rods and tensioned silk threads that create a constantly updating three-dimensional relief map of the Handle and its surrounding tunnel networks. Each strand represents an active path with collapsed or unstable routes flagged and rerouted in real time by unseen pulleys. The building also serves as a training hub for elite delver guides and cartographers. Seasoned delvers come here to look for guides to aid them on different expeditions into the greatclub tunnels.

Threadspire Archive rises like a woven needlepoint of chitin and copper, its central tower spiraling upward in jagged, asymmetric tiers that resemble the curling antennae of a moth. Etched beetle-carapace panels inscribed with runic topography shimmer faintly in the Hilt’s heat-haze, shifting under different angles of light like a lenticular map. A network of tight-rope-like lines—colored silk cables—stretches from the tower’s spires to adjacent rooftops, each bearing color-coded flags that flap in sequence to indicate tunnel alerts. At the broad entry arch, rows of lanterns burn blue and orange over a floor mosaic that depicts the greatclub’s cross-section in staggering detail. Passersby linger to marvel, but few step inside without purpose.
