Psionic Trio

I'd like to see psionic classes in play. I planned this as a one-shot, but we'll see if there's general interest in going on with the story.

The Setting

In any world, people want to travel from one place to another. However, outside of the stable regions, our continent has been invaded by some unknown force, making the general landscape volatile and dangerous. There are Rifts that open to other worlds, allowing their environment to seep into this one, including 'natural' phenomena and creatures. People who can't use psionics (no manifester levels) are extremely susceptible to these dangers, so they seek psionically awakened ones to guide and escort them from one safe region to another.

Whether out of altruism, financial gain, duty or desire for excitement, the characters are a group of such guides currently in Earth-helm. By chance, there's a small group of nobles intent on leaving in a day, not waiting for a trader group. They are willing to pay much better than traders, only they know why.
