- A church with a broken steeple rises out of the desert. On approach, it seems to have been abandoned for years but the scent of fresh blood and rotting meat hangs in the air. The inside is untouched except for a strange geometric shape drawn on the altar in blood.

- The party breaks into an abandoned shack to escape the freezing wasteland night. Inside is a pile of empty supply tins and skeleton with no legs clutching a journal. The journal is in a language the party does not know but appears to be a spellbook.

- A child is found wandering the desert. They have no supplies or equipment but the clothes on their back and an empty canteen. They don't respond to anything and continue walking south unless someone grabs them. If questioned, the only thing they do is point back where they came and shake their head.
