“ On a location with numerous webs, and at least one big spider, there is a something inside a cocoon. It is humanoid in shape, still moving. If the heroes free it (not before they kill or drive away the spiders), they meet a ... zombie!
The poor zombie wandered the dungeon alone, and tried to kill a big living creature (= a spider). The spider used the usual treatment, even if this victim did not look tasty. The zombie can be easily killed as any other zombie. It got but several doses of spider-poison, so can be something worth if it is extracted. You can mention to a druid or ranger the fact the spider had no poison anymore.”
“ A flower possibly in the plains or maybe all over that is always tilted towards a certain place. Sunflowers. Could possibly follow the sun or could be forever facing a certain position because of something that happened, either the air forcing it that way and it staying, the fire was so strong that the flowers faced away from it. It could be that in one spot a large fire was made or a fire war where many fire elementals were destroyed by the True Gods and radiating out from that point all of this flower is facing away from it so no matter where you are you always know where this place is by seeing which way the flower is facing away from.”
“ There are ruins, scattered about the world, and all are sealed with unbreakable locks.
When all of these locks suddenly open, what emerges?”
