Yes, Teresa, there CAN be more than one, but to get to them you would have to travel into parallel universes. Such travel is very, very complicated and difficult and should not be undertaken without proper equipment and training.

The best way is to gird your loins with a gladius, a targe, a complete set of bagpipes (the big Scottish war pipes are best), a parfleche containing dried corn, dried meat and/or fish and/or berries, warm clothing, at least 10 liters of water or other drink of your choice, several feet of logging chain, a lariat, two or three bodhrans, and a copy of the complete writings of either Paul Dirac or Ted Gissell.

Properly outfitted, you must find then find a rabbit warren, as the tunnels in bunny havens are the easiest (and only non-lethal) way to journey to these other universes (the others involve black holes, blue event horizons, and stuff like those). Crawl through the bunny tunnels (old-time MOABites call them "bunny tunnies"), following every twist and turn, and eventually you will see a White Rabbit chasing a pre-pubescent girl. Follow them, and after you pass through the place where The King is sleeping with Sir Francis Drake's drum, turn left and continue straight on until morning. And there you'll be.

Tweed and Khandu went off on such a journey together, and they only made it part-way back. That's why they're not around here as much as they used to be -- they're only partly with us.
