The Wild Hunt. A supernatural group of hunters that chase after their game, dooming anyone who sees them. Supposedly led by Odin sometimes. Would there be a way to mimic this and hit harder if we go South?
Funny thing about that.
AFAIK, the association of Odin with the Wild Hunt is mostly a later addition/link made up in the 19th century in connection with the Springtime of Nations and backlash to imperialism, when a lot of nations were "recovering" (frequently:inventing and rewriting) their own native myths and cultures and traditions.
The old Norwegian equivalent of the Wild Hunt is
Oskoreia, original etymology and meaning unclear, three candidates are "the awful ride" or "the drunken ride" or "the thunderous ride". It's composed of nisser and troll and other wild creatures on fire-breathing horses, sometimes supplemented with the unquiet dead and the damned, and they most commonly show up in the depths of winter, particularly the liminal time between Yule (Christmas) and New Year to wreck things and kidnap people. It's an overgrown raiding party of monsters and criminals grabbing whoever or whatever isn't secured.
The old stories are very loose and inconsistent, featuring various supernaturals as the leader. One is the witch Guro Rysserova ("horse-tail" or "big-butt"), who in one account recruits Sigurd Dragonslayer by asking him whether he'd prefer to be at the front of Oskoreia or at the back of Heaven. Another is Nøkken, the naiad/nixie/kelpie who drowns people in streams and lakes when not riding around to fuck people up.
Around the 19th century, Odin was glued onto it with the fake etymology
Åsgårdreia (the Asgard ride),
sometimes Thor too. The whole thing was rebranded a bit and given more of a narrative arc and a faerie structure of going after people who have broken some magical Rule, like violating guest-right or not feeding the nisse or letting the children stay up too late. Yes, really.
"Go to bed or the Wild Hunt will get you." In later versions, the Christian cross painted on the door and the people and even the farm animals keeps the Hunt away (might have been cribbed from vampire stories + Ash Wednesday), as does gunfire and fireworks.
Take all this with a grain of salt, I am
very briefly and loosely summarizing a large body of folklore.
