Well, the first world, Propero, involved nightly encounters with creatures called Shadows. We were able to summon Personae, manifestations of our psyche, to fight them. Not to mention we also dealt with strange events that happened every full moon.

The last world I was in, we were actually brought in by a rebel group called the Initiative. It was much more futuristic world but it was ruled by a global tyrannical power, the United Earth. Our mission was to dismantle the power by messing with key events in the past to stop it from being created. We often hit many setbacks but, we somehow managed to win. It's still hard to believe we managed it pull it off.
