The Opening

Across Jorthiel’s grain hills, sections of the ancient Gild-Way are breaking through the earth like drowned tombs, spilling cold mist and blue fire into the fields. The latest rupture has opened beneath a canal road, and Archivist Orelia Vane believes it connects to the Sunken Archive, where a relic called the Siphon Key may be waiting. If the Obsidian Tribunal reaches it first, the next collapse may swallow an entire harvest district.

Set the Scene

The party reaches a grain road buckled by a fresh rupture. Wheat bends toward a jagged sinkhole, though no wind moves across the hills. Beneath the collapsed road, blue-white light flashes through black water, and every few heartbeats the sound of a distant bell rises from below. Orelia waits beside the breach with a satchel of damp notes, while frightened teamsters pull at a mule whose shadow keeps pointing toward the hole.

Archivist Orelia Vane

Orelia approaches the party at the newest collapse site, first offering urgent evidence, then asking for protection while she enters the exposed transit pocket. She frames the mission as a historical recovery effort, but her fear makes clear that something more dangerous than lost records is waiting below.

Stakes

If the Tribunal obtains the Siphon Key, it may redirect or amplify the failing Gild-Way network, threatening Jorthiel’s canals, grain roads, and regional supply lines. If the party fails to preserve the archive evidence, later factions may dismiss the sabotage theory as panic or political manipulation. If the archive collapses unchecked, the route to Grand Hollow may become unstable, isolating the party from the next stage of the campaign.

Ticking Clock·The archive floods over approximately 6 hours of in-world time. Once the party enters the deepest sections, each major delay, failed stabilization challenge, or extended rest accelerates the collapse. The Lost Indices become unreadable after the preservation gallery is fully submerged, and the Tribunal completes its extraction ritual if the party spends too long securing earlier chambers.

Background Lore

Months ago, canal engineers excavating beneath Jorthiel’s grain hills breached the Sunken Archive, a pre-Compact vault built around an ancient Gild-Way transit junction. The breach exposed flooded chambers, fragmented engineering records, and a sealed device called the Siphon Key of Ignisvorn. Since then, collapsed Gild-Way transit pockets have begun surfacing across the region, disrupting roads, irrigation channels, and grain shipments. The Obsidian Tribunal has entered the archive through hidden routes, seeking the Key before Jorthiel’s authorities understand what it can control.

What the World Knows

Collapsed Gild-Way transit pockets are surfacing throughout Jorthiel’s grain hills, disrupting canals, roads, and harvest routes. Archivist Orelia Vane has traced the newest rupture to the Sunken Archive, a pre-Compact vault breached by canal engineers months ago. The Obsidian Tribunal is also searching for the Siphon Key of Ignisvorn, an ancient device that may control the failing transit network.
