I think I've included all of the suggestions in the poll below. Just vote for the idea that you like best. Please go back and read the comments for this entry before voting, because I want you to make informed decisions, and those with the ideas definitely explained them better there than I did in my crude summing up.
And yes, you can vote for your own idea. Of course!
So here it is: Assign the following roles!
Keppra- misunderstood frogman or game of chance?
Atenolol- flame kingdom or magical gems?
Alphagan - inept wizard, fire-breathing bird, or mountain range?
Avelox - bird familiar or lovable scoundrel?
Xalatan - "old wives tale" or demon dog?
Lipram - helpful gnome/troll or young peasant with a grudge against one of our heros?
Lanoxin - incredible fabric or lake with a secret?
Guiatuss - cave maze, volcano, jolly old man, cat, or spellbook?
