Wiggles

Smallest and worst of the voles. They are flying worms less than the length of a finger, loosely spiraled, that hover in midair, then zzapp forward, leaving a vacuum behind them. They drill through anything that gets in their way, instantly, which can be uncomfortable for animals. They are indifferent to external things, but can be killed by crushing, burning or cursing. Periodically they swarm, radiating out in a great sphere. When one of them gets where it�s going, it incubates for a new Swarm. Thus it is important that every member of a Swarm be exterminated � and just about impossible. In Mundania they are much smaller and swarm mainly in buildings, and are contemptuously called termites.

Will-O�-The Wisps

Faint lights that dance about at the edge of perception, they are great teasers who will lure unsuspecting people into trouble. Herman the Hermit was able to communicated with them, and with their help saved Xanth from a wiggle Swarming.

Wooden Knob

An unidentified object that reverses the emotion of those who touch it, making enemies of friends and vice versa.

Wraith

A nocturnal ghostlike creature that roams at night.

Wyvern

A small flying dragon with a barbed tail and only two legs. Vicious. Not very smart, as any expendable weight is sacrificed in the interest of lightness, and the heat of their fires tends to fry what remains of their brains.
