I need another item in my "campaigns I want--nay, need--to run" list like I need another hole in the head, but Ken Hite just came along and forced me to add one anyway:
THE GRYPHONS OF CALYFERNE
Cadamosto returned to Portugal in 1456 with staggering news: He had discovered the island of Antilia, far to the west across the Atlantic Ocean. Better yet, he had heard of other islands, rich in spices, gold, and cities -- Hy-Brasil, Cibola, Estotiland, Norumbega -- and greatest of all, the legendary Calyferne, ruled by Amazons and guarded by gryphons! A chain of Indies stretches to the Kingdom of Prester John himself, and to the lands of the Great Cham of Asia, and you have a copy of Cadamosto's map and a ship that will take you west to find them. You are adventurers of the Order of the Golden Fleece; some learned in the wizardly arts, some practiced sailors or sell-swords, all willing to explore these new isles for Prince Henry the Navigator, and for treasures magical and mundane.
Do not be fooled by the cunning historical persiflage above! By old-school fantasy request, this game will feature: beautiful princesses, villainous pirates, aloof elves, clouds of black powder smoke, fearsome dragons, swarthy dwarves, enigmatic glowing gems, leering mandarin-viziers, heaps of gold, alabaster cities, hyena-headed gnolls, subterranean passages, sword-fighting, missing idols, magic rings, cruel giants, and the Mighty Kraken. Plus griffins and California, just like the title says.
He's planning on using a hack of Ars Magica if he runs this. Me, I'd probably go with GURPS Dungeon Fantasy, is second choice.
