My inspiration for this thread was a television program on one of those suicide cults. This one had some weird belief that the group's suicide would lead to the end of the world. While obviously, that wasn't true, it got me thinking about my favorite cosmoscidal pointy-eared people, and what would happen to the mundus if the wheel of life stopped turning. Would the whole machine break down? Would it wait for new bodies to 'naturally evolve'? Would Arkay just step in an not allow any of this to transpire? What do you think?
Obviously, I don't expect any solid answers here, just speculation. This is unknowable, but very guessable.
