Something is terrorizing the streets and backalleys of Portown! The dockers and the homeless are terrified, and even the Assassin's Guild is worried!

Although a big deal was made about cornering a doppleganger in a storage complex near the docks (Part One), the authorities claim that they have caught the "Marrowbeast" and all is safe once again. But the truth is, the disappearances and the murders have increased in frequency and ferocity!

But your PCs, hanging out at the Green Dragon Inn, can't get a word in edge-wise. Yes, they know the truth, but the people don't want the truth...

...and then they're hired by Gerron Dwelvenminter, dwarvish son of the famous Dwarven Miner and Archaeologist Garron Dwelvenminter to recover his father's body from an ill-fated expedition -- in the heart of Portown! Down a disused drainpipe, Dwelvenminter discovered an ancient crypt, broke it's magical seal, and fell to his death.

Coincidentally, this all happened just before reports of the Marrowbeast first surfaced - right about the same time of the first in a series of disappearances and killings...
