I could have sworn I’d seen a vampire movie (but I can’t remember which one it was) where the heroes had to stake the vampire at a crossroads and then behead it.

This seems to do the trick, why not.

In Brazil there is also the idea of meeting not only the devil but also god in crossroads. There are stories talking about really traffic heavy crossroads where it is said “everyone and god” passed trough, and of patient people waiting there until god Walks buy and talks to them about their grievances.

I liked this article, but I was slightly disapoitned that it focused a bit too much in the encounters and not in the crossroads, their uses and significance itself (i.e.: Why did crossroads aquire this significance)

A two inch tall furry monkey wearing slippers and transforms into a hideous werewolf, no less.

I don’t think I’m aware of any, but the British custom of burying criminals at crossroads (and the idea of Mad Martigan being caged at one) could be a great hook for games. Every crossroad is an opportunity to speak with dead, but it’s also a chance to have undead at your throat. The iron of the cages or rails could easily prevent the dead from leaving, building on some folklore of iron as a ghost deterrent.

Great article!
