In Their Veins

The Adventure

The plague isn't back. It's a tool. And the man holding it has been patient enough to wait for exactly this moment.

Ahmadou's Gate was once a wonder. Its bioluminescent ink lit books and art through the darkest hours, a city that turned night into something worth seeing. Then the plague came, took half the population with it, and left the rest to pick through the wreckage. They survived. They recovered. And now the dead are piling up again.

The city remembers. Half its people went into the ground, and the ones left standing never forgot what it felt like to watch someone rot from the inside out. They rebuilt. They moved on. They told themselves it was over.

In Their Veins is a mystery adventure for 5e. The characters arrive in Ahmadou's Gate mistaken for healers from a neighboring town. By the time the real healer shows up, someone is already dead and the accusations are flying. The deeper they dig, the more the city's fragile recovery begins to crack: a sadistic physician with questionable methods, rats carrying a familiar sickness, paint that makes people dizzy and strange, and an abbot with his hands in all of it.

What's Inside
Setting Ahmadou's Gate: a city built on bioluminescent ink, where the same organism lighting every lamp and book is now turning up in the veins of the dead
The Mystery Someone is reintroducing a plague that nearly destroyed the city a generation ago. The characters arrive as outsiders, which makes them suspects first, and investigators second.
The Threat The city is already on edge from a plague that decimated it just a few years ago. It will not survive another of that magnitude.
The City Ahmadou's Gate remembers its dead. Every NPC carries the weight of the last plague. That grief makes them dangerous, unpredictable, and very easy to manipulate.
The World Set in Zaelhara, a continent of Umbraeth. Drop it into your existing campaign or run it as a standalone one-shot.
Encounters 1–2 combat encounters give the story room to breathe. The real danger is what you learn, not who you fight.
