Some of mine:
- A world very much like our own must adapt as super powers arrive on the scene. Are these new super powered people friend, foe, or something in between, and how will the world react to the amazing things they can do?
- The PCs live in a remote village that has suffered for weeks from cattle raids by a neighboring community. When the PCs move to investigate and retalliate for these raids they find that they're not being attacked by human beings, and that there is a lot more at stake than a couple of cows.
- Rokugan tears itself apart when the Emperor dies before expressing which of his identical twin sons will succeed him and rule the land. The PCs must take sides as both brothers gain forces and seek to take the throne their father clearly wished for them to have.
What is yours?
