A Most Non-Non-Non-Heinous Excursion
The PCs are characters from history, expressed with three simple descriptors: a skill, a physical appearance, and a state of mind.
The setup: the characters have been abducted by two mischievous young gods of time, and transported to the future. There they have been dumped in a city full of wondrous magic and told to amuse themselves for a few hours while their hosts go on some unspecified errand. With no companion from their own time they band together out of mutual terror. What will these travellers do? Will they hold onto their last shreds of sanity long enough for their mysterious and youthful benefactors to return them to their own time?
