Sneak preview of my Monte Cook/Planescape interview is up

[Gez]

I plan to "introduce" my players to an item down the road that is essentially a divining rod for portals scattered across the Realms. The item/artifact is alien in origin but they won't know much about it at first. It leads them to various portals but they don't know why.

Since it's alien in origin, it has been lost by an alien. And since it's not on Planet Alien (tm), then it has been lost by an alien who was himself lost.

They'll also have to discover why the artifact is leading them to these portals and what will happen if they don't enter the portals. Ooh, I'm nasty.

So, this is a planar GPS compass which is programmed for returning home. It will lead the valiant heroes toward Planet Alien (tm). And if they don't enter the portals, they'll stay stranded forever on their homeplane, never returning to the safety of Planet Alien (tm)!
