Hi! Hoping someone can find a story that I haven't been able to locate in a while. The main thing I can remember is that Sam and Dean end up on a hunt that has to do with a modern Indian tribe that is being hassled by ghosts of an ancient tribe. In order to make the hauntings/problems stop, Dean ends up being tested to see if he is a worthy warrior. I remember there was a group of people (maybe a tour group) along with Sam and I think the modern tribe's female shaman (who was leading the tour group) watching Dean go through the "tests". I remember that Dean gets pulled behind some horses. He goes through a couple of other things too but I can't remember them. This may also be taking place after Dean was already pretty run down from a previous hunt, but I'm not sure. Would greatly appreciate it if someone can recall this story.
Also, I will gladly take any recommendations where Dean goes through some type of trials or tests or whatever, whether to prove himself or to protect/save Sam. Gen or Wincest gladly accepted. Please no WIPs and self recs are always welcomed! :)
FOUND: Specific story found, thank you. Still open to recommendations for similar stories.
