If we are talking about the one in Castles Forlorn...I especially dislike that one, and the very reason why can be spotted in the first line of its description "...a powerful force acting for good." I want to know where THIS idea came from because its completely and totally unrelated to anything I've ever seen or read about the Wild Hunt. At the best, the Wild Hunt is a force-of-nature type occurance, in that it is neither good nor bad, it just is. Other interpretations, its a sinners eternal punishment (as either the hunted or the hunter, depending), or its lead by a great evil itself. I've never seen any version where the observance of the Wild Hunt was anything but a cause for worry, even if it just passed you by. Even the most benign versions, like Odin's hunt, usually signaled weather changes or the coming of war or famine.
Also, the hunter in that module travels on foot. And that's just blatant horse-poop. Nobody in a Wild Hunt gets away by following the dogs ON FOOT.
Really, considering the pseudo-Celtic origins of the entire domain, I don't know why they had to go and drag the name of the Wild Hunt into this, when there were any number of good choices for a 'last desperate attempt to stop the evil that is loose amongst us.' Especially considering they claim the Wild Hunt is a force for good, and then NOPE, SURPRISE, Its been corrupted by Ravenloft! Which isn't a surprise considering its source has never really been identified as a force for good.
Heck, this hunt is actually pretty close to the original version Gary Gygax detailed in Deities and Demigods. How's that for corruption? In that version, when a great evil walked a land tended by Celtic druids, there was a chance the Hunt would spawn. The Hunt spawns 10 miles from the 'source' riding directly at it. Any being that seeks out the noise is automatically ensnared, and a 25% for any others spotting the Hunt, with a 10% chance to be the hunted instead of a hunter. If the source is spotted before any others become the hunted, the source is then hunted; otherwise the hunt turns on the nearest game animal. Either way, the hunt carries on for 10 miles after passing the source (and if the source is inside a building where the Hunt won't go, it will pass within inches of the structure) and then it all disappears. It even explicitly states that Hunters will do things out of their control, including the possibility a paladin will hunt and kill innocents as a result of the Hunt.
It closes the entry by pointing out that the Hunt most often appears in tales where it fights and is killed by the hero of the tale, implying that the Hunt is neither good nor evil...it simply is.
