“ A small, enchanted chest, 2 feet on a side. It is of some dark wood with fantastical images graved upon it. Worn leather straps act as hinges and a simple toggle keeps it closed. Anything placed within it, with the lid closed, becomes accessible to anyone with one of the other 5 identical chests. Once it is taken out of any one of the 6, the chest is empty again. Perfect for passing messages or small items between widespread groups, such as ships at sea and their ports of call or generals on the field of battle.”
“ Historicly, we have had plenty of rl groups like the Taliban and the Puritans who supressed anything which was in any way fun. What if there was some group that was the opposite? (which in time would cause problems of it's own for the civilians under their control.)”
“ After the PCs defeat (or force the rapid retreat of) a villanous necromancer/demon summoner, they discover a book. This book outlines how to summon a demon whose power increases according to the size of the summoning circle used to summon it. And after the PCs examine a map of the country, they find that the layout of the cities and roads match up with the required summoning circle. In fact, the final road that would complete the circle is currently in construction.
With anyone who can find out about the circle and the ritual to summon the demon able to somehow make the final road/line, and destruction of the cities and roads currently in existence out of the question (unless this is an evil campaign- that removes the moral quandary), how are the PCs going to solve this problem?”
