Apart from the Holy Grail, Fountain of Youth, the Ark of the Covenant and El Dorado, what other legendary treasures are there?
There are a few here: http://64.233.169.104/search?q=cache:axaB1XFE8GEJ:e23.sjgames.com/media/PJR051_preview.pdf+Legendary+Treasures&hl=en&ct=clnk&cd=1&gl=ve&lr=lang_en&client=firefox-a
come on! I need more T-T I'm currently developing a plot in which the Holy Grail can reveal the location of the Ark of the Covenant, and the Ark of the Covenant can reveal the location of a kewl treasure. I was going to use the fountain of youth, but I can't 'connect' it with the other two treasures.
There's supposed to be a big gold mine here in Arizona, the Dutchman mine, that has been lost and never found by anyone. It's not as famous as say, the fountain of youth, but that just might make things more interesting if you use both famous and not-so-well-known lost treasures together.
There's a fabled treasure on Hermit's Island in the Apostle Islands of Lake Superior. I learned that on vacation this week...a little simpler, but still good fun if you want to use it.
