Sunrise Over the Black Lake

Things within or around a lake tainted by evil. Roll (d12):

1. It is believed that the memories and knowledge of dead sorcerers can be gathered and extracted from the waters of the lake to make potions. 
2. Message in a bottle floating in the lake. Message inside says one of the PCs is cursed. Judge to randomly decide which PC, who then suffers a -4 on Luck rolls for next 1d4+1 days. Curse can be lifted by magic. 
3. Eyeballs on the end of stalks around 1-2’ high grow around the edges of the lake. The eyeballs blink and always watch the PCs. The eyes have been extracted from nearby villagers. 
4. Children from a nearby village laughing and playing together at the water’s edge. They have black boils over their bodies and black puss is drooling from the mouths. 
5. A huge boulder smeared with blood. 
6. The water of the lake looks like it’s boiling with steam rising, but when the PCs get close, it is actually freezing cold. 
7. Crystal clear water, with what looks like two-headed mermaids with golden tails swimming beneath. 
8. Music and happy singing coming from a distance. 
9. Animal/plant hybrid creatures feeding with their intestines coming out of their stomachs and going into the ground. 
10. A life-size statue of a person pointing in a direction. An absurd riddle written on the base of the statute gives a clue to the PCs. 
11. Hundreds of large eggs, about the size of a human. Some have already hatched. 
12. A polished marble staircase, leading underground.
