The Opening

Bellwater's aqueduct has turned black, and anyone who drinks from it suffers nightmares or worse. The magistrate will pay you to find the source before the town runs dry. Witnesses claim that lanterns have been seen moving beneath the spillway, where no passage should exist.

Set the Scene

Rain falls over Bellwater as the party is led to the aqueduct's lower inspection gate. The usual rush of clear water has become a sluggish black stream that reflects unfamiliar stars even in daylight. Magistrate Elian Voss waits beside several exhausted workers while Nessa Vale points toward the sealed spillway and insists that someone is moving below it.

Magistrate Elian Voss

The magistrate approaches the party in public, offering an immediate payment and legal authority to enter restricted parts of the aqueduct. Sister Maelin quietly asks to accompany them, warning that the town's official story is incomplete.

Stakes

If the party fails, Bellwater loses its only reliable water source, the Blackwater Avatar gains freedom to reshape the watershed, and the town's leaders may respond with violence or authoritarian control. If the party succeeds, the aqueduct is restored, but Bellwater must accept that its prosperity depended on a broken promise.

Ticking Clock·The black water reaches Bellwater's main reservoir after approximately 24 hours. Once the reservoir is fully contaminated, purification becomes far more difficult and the Blackwater Avatar can manifest at full strength.

Background Lore

For generations, the riverside settlement of Bellwater has relied on the Silverroot aqueduct, an ancient stone channel that carries clean spring water from the Thornwake Hills. Three nights ago, the aqueduct began running black and metallic, livestock became agitated, and several villagers suffered vivid nightmares. The local magistrate believes the contamination is the work of bandits, but old records suggest the aqueduct was built over a sealed pre-human shrine.

What the World Knows

Bellwater's vital aqueduct has been contaminated by an unknown force. The town council believes saboteurs are responsible, and a frightened witness has reported strange lanterns beneath the sealed spillway. The party must investigate the aqueduct, find the source of the corruption, and prevent the settlement's water supply from being lost.
