"You see, THAT is why I chose this particular reality to hunker down in," Pupp explained.  He
very casually flicked his wrist.  A small, bewildered rabbit appeared in his outstretched hand.

"On Earth, i'd merely create an illusion that there was a rabbit.  The ambient magical energy
in our universe is very faint."  He stroked the rabbit between the ears, calming the animal,
who now started looking around the room looking for food.

With another flick of the wrist, the rabbit was gone, leaving nothing but a small puff of
purple smoke.

"This world is absolutely SATURATED with magical energies, so rather than create just the
illusion that a rabbit is in my hand, I actually can create a living creature where before
there was nothing."  He rolled his eyes, correcting himself, "Well, not exactly nothing.  It's
actually pretty complex involving base elements from the surrounding area and chemistry and
such, but because of the heavy magic saturation, it's no effort at all."

Katze had noticed from the first moment she stepped onto the Discworld that she was utterly
enveloped by magic.  Stepping out of the 'gate, it felt kind of like walking into a heavy fog
which you can't see, can't smell, and which has the effect of making a mage feel like they're
taking a constant methamphetamine shower.
