[quote=Kaga] I've just brainstormed about a dozen possible challenges based off of Doctor Who and Homestuck (each). I'll probably give them all a bit more thought later tonight to see if I can narrow those ideas down to the ones that'll probably work the best.

Do any of them involve Fearing the Dark, not Blinking, Extermination, Upgrading, or a dozen other horrible things that exist in the Dr. Who universe?
