Hadean Lands full-page, full-color map poster! This map will be part of the game docs, but this poster will be larger and prettier. (Plus the game for Mac/PC/etc, and iPhone, and the postcard.) (Belated note: the poster will be added to all rewards $50 and larger.)
Your name will appear in Hadean Lands, in some form, as an ancient alchemist or sage or spell-rubric. ("The Sulphuric Dragon of Andricus Plotinus", that kind of thing.) (Plus the game for Mac/PC/etc, and iPhone, and the postcard.)
You will receive the source code of the game, for your edification and amusement, as a printed volume. (Plus special credit as Hero of the Dissolution, and the game for Mac/PC/etc, and iPhone, and the postcard.)
A mystical alchemical calligraphical formula of ancient (made-up) lore, hand-written on (freshly-made) ancient paper. With incomprehensible mystical symbols! (Plus special credit as Hero of the Coagulation, and the game for Mac/PC/etc, and iPhone, and the postcard.)
The traditional Kickstarter "I'll fly out to visit you and bake you cookies!" offer. (Continental US only please.) We can hang out and talk about IF, or play the game together, or go out for Peruvian -- whatever's agreeable. Plus all of the above.
