The best thing for prophesies are to leave them very VERY vague. Even, like Set mentioned, not even saying children of an eclipse, but calling them children of a black sun. Yeah, it's pretty obvious what it means, but if I don't want the characters to be the actual prophecy later on, I can always change it to NPCs from a world that has a black sun.
Cheesy, yes. But still an out.
I am liking the idea of some sort of object being used to distinguish the players as the ones in the prophecy. Im thinking perhaps something akin to the compass pointing in thier directions.
This has given me a LOT to think on. I appreciate the suggestions.
I hadn't intended this to be such a MAJOR hook in the story, but merely a way to get the characters working together. But, this is turning out to be a pretty good sounding device.
I've gotten tired of the whole meeting in a tavern scene, or being hired by someone to do something. It all is too cliche and contrived.
Thanks again, all.
