Not every monster waits in a dungeon.

The waterways around Lacton have become dangerous. Wildlife is disappearing, river traffic is being attacked, and frightened sailors speak of a creature lurking beneath the surface.

When a nervous wizard hires the Heroes to accompany a heavily protected crate on a three-day barge journey, the task seems straightforward enough. Guard the cargo, enjoy the voyage, and collect the reward.

But the river has other plans.

As strange signs mount and the water itself becomes increasingly hostile, the party must deal with hungry scavengers, dangerous river conditions, and a powerful amphibious predator that strikes from below. What begins as a routine escort mission quickly becomes a race to recover a lost cargo before it vanishes into a labyrinth of underwater caves.

Perfect for groups looking for a mix of roleplaying, exploration, skill challenges, and exciting tactical combat, Waters of Wrath offers a complete adventure that can be run in a single session or dropped into an existing campaign.
