my campaign takes place on a world with 5 moons, one for each of the elements. earth, air, fire, water, and aether. there was a 100 year long religious war that culminated in the clerics of 5 races going to the moons for pure elements to use in their war. the gods were insulted by this afront and invasion, and cursed the 5 races. the curse ended the war. what i'm having trouble with is firguring out two of the curses. this is what i have:
the dwarves went to the earth moon and used the power of the pure elemental earth to create powerful automatons. they were cursed with stone-skin affliction. Older dwarves, especially those from royal families or those descended from the old priest warriors, are likely to contract a wasting illness where the skin turns scaly and hard like stone. Eventually the afflicted can no longer move or care for themselves. Finally, if they don't die, they turn to stone.
gnomes went to the fire moon and used pure elemental fire to control and summon red dragons. they were cursed with exile. the gnomes' kobold shock troops and dragon servants revolted, took over the nation and the gnomes fled. They now live in exile never to return to their home and never to have a homeland of their own. Any gnome settlement over 100 is doomed to failure, collapsing to the chaos of the curse of exile.
Orcs were the most powerful (and civilized) wizards in the world. they went to the moon of aether and used the aether to cast True Magic that permanently altered reality itself. They were cursed with insanity and now roam the world as near mindless barbarians.
that's all i got until i run dry. i have two elements left, air and water, and two races left, and i'm not sure what to do. i had orignally intended to use elves with air, they used air to call storms to attack their foes, and were cursed with fould weather. their northern homeland is under constant assault by the elements. and then humans with water who used the power of the element to call floods and droughts against their foes. but i couldn't think of a curse for that one. so. suggestions?
