The Traveler's Curse alters Xen'drik temporally and spacially. The effect is that adventurers will find that maps sometimes fail them. On the positive side, sometimes the curse will cause a person to arrive where they need to be earlier than they anticipated. Or even better, the curse can cause a treasure seeker to find an unexplored ruin filled with treasure. No one knows what causes the curse. Interesting, it has less effect on natives to Xen'drik, like drow and giants. And strangely, the Traveler's Curse has no effect on thri-kreen.
