I just found out about the Wild Hunt tonight, and it really sounds fascinating. I've been trying to find information about it, and I thought /r/AskHistorians might know a few things. I'm interested in finding good resources online that are free, and maybe scholarly papers that aren't blocked by a paywall. I can't afford to buy any books, except for that I am purchasing Phantom Armies of the Night: The Wild Hunt and the Ghostly Processions of the Undead by Claude Lecouteux. It got some good reviews on Amazon.

Anything you can tell me about the history, origins, manifestations, ect, about the Wild Hunt would be greatly appreciated!
