Six Befouled Ponds

1. Filled with blue-green tar. The tar isn't poisonous or anything - but it's extremely easy to be trapped and drown in it. And its fumes are hallucinogenic.
2. The water is rancid and grey. Various toxic molds grow on the pond's edges. There's a huge Pink Leech hiding at the pool's bottom.
3. The water is crystal clear and suitable for drinking. Unfortunately, there are at least seventeen Jade Shamblers growing in the tall, sapphire grass surrounding the pond.
4. The local tribe is using the pond as a sacrificial place for their gods. Once each season they drown some of their cattle in deep, dark waters. Each full moon, the undead oxen and cows crawl out of the pool.
5. Ground around the pool is covered with dozens of statues of various animals. Some of them seem to be in perfect condition, while other are shattered and/or heavily weathered. Any living being that drinks from the pond must save vs Magic or turns into stone within 1d4 minutes.
6. The thick liquid in the pond is of brown-red color. It emits a horrid stench of death and decay. Three monoliths of polished black stone surround the pool. Each sunset, three Iron Demons descend from the blood-red sky to drink from the pond. Even though they seem to be hostile towards any other being, it's said that they can grant power to those whose souls are absolutely corrupted and blackened by sin.
