What they see

A collapsed root tunnel opens into a sloping stair filled with ankle-deep rainwater. Broken expedition gear floats beside carved warning stones, and a fresh rope descends toward the flooded levels below.

Features

  • Moss-covered entrance idols depict people offering bowls to a storm-faced spirit.
  • The rainwater flows inward even when the passage slopes upward.
  • A rusted expedition winch can lower or raise a rope bridge.

Notes

Characters who inspect the idols can learn that the guardian was honored, not feared. A successful Religion or History check reveals the sanctuary's original symbol: an open hand beneath a falling line of rain.

The place

What it is

The Weeping Root lies beneath the Verdant Maw, a seven-level sanctuary carved into the petrified root system of a colossal world-tree.

Atmosphere

Endless rain drums through stone, root, and drowned timber.

The threat

Nhalu, the Gentle Deluge, is both prisoner and disaster.

History

The Verdant Maw's first river clans built the Weeping Root inside the fossilized roots of an ancient world-tree.

Rumors

1d5
Roll a rumor

  1. 1A drowned temple beneath the Verdant Maw still protects the rainforest from armies, but its guardian has begun choosing which villages deserve rain.
  2. 2Marra's expedition found a treasure that sings during thunderstorms, and Pell plans to sell pieces of it to foreign kings.
  3. 3People who sleep beneath the rainforest hear a child crying in the rain. Those who follow the sound return speaking in several voices.
  4. 4The old clans did not imprison the rain spirit because it was dangerous. They did so because they feared what it knew about their wars.
  5. 5A crocodile made of green glass guards the flooded road below, but it lets oathkeepers pass unharmed.

Corridors

4

  • Between rooms 1 and 4

    Thin streams run uphill along the root walls, carrying leaves, fish scales, and scraps of ancient writing toward deeper chambers.

  • Between rooms 3 and 7

    Petrified root arches bear carved faces with open mouths. When adventurers pass, one face occasionally exhales warm mist or whispers a single word.

  • Between rooms 6 and 10

    Flooded crawlways branch into darkness. Their water level rises whenever someone lies aloud about their reason for entering the dungeon.

  • Between rooms 10 and 14

    Blue sparks leap between exposed root fibers during distant thunder, briefly revealing footprints that do not belong to any living creature.
