From the update:
There Be Dragons! Every map has that part marked on it, warning weary travelers not to go beyond, but we stand here, daring you to! When we reach this level of funding, Vampire and Undertaker level backers can add both of these Dragons, the sinuous Shadow Dragon, and the vile Fire Dragon, to their pledges by increasing their pledge by $15. Each Dragon is over 3" tall, and would count as Huge in the world's oldest Fantasy RPG.
