Ruthless thugs assault the city's temples, stores and alchemist laboratories to rob all kinds of magical liquids. These thieves belong to The Testudine Testament, a cult based around the worship of a gigantic speaking turtle living beneath the city. What the cultists don’t know is that they’re being led on by a swarm of cranium rats pulling the strings to fuel its addiction to magic.
A duped alchemist asks the characters to track down and deal with the criminals that ransacked her laboratory. While investigating, the party finds its way into the seedy underbelly of the city, where the characters learn of mysterious gatherings taking place in a neglected part of the sewers...
The Testudine Testament is a one-shot for 3-5 characters of level 4.
