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.
Something lives in the fog in a certain region and travels with the fog. Kidnaps or kills, or is simply heard and "felt".
