Gap Dragon

One of the most formidable monsters of Xanth so I figure he gets his own listing. He is low-slung, with a triple pair of legs, and iridescent metallic scales. Though he has small wings, he is landbound, and travels by whomping along. He destroys all creatures unfortunate enough to blunder into the Gap. Accidentally youthened to baby status, he was befriended by Ivy, who named him Stanley, because he is a steamer. During his second youth, his female counterpart, Stacey or Stella Steamer, patrols the Gap.

Gerrymander

A creature with an irregularly sinuous body, small wings, claws, tail, and a lizard head. It repeats: "I convolute, I divide, I conquer, I surround, I select, I cover whatever territory I need to hold power!" And it does. This monster also flourishes in Mundania, where it deprives common folk of their part of government.

Gnomes

Humanoid folk a third the height of human beings, who reside underground and mine for gems. The males are surly, but the females, called gnomides, are nice.

Goblins

Goblins are ugly humanoids half the height of a man, with large hands and feet. Their heads are as hard as stone, so it is impossible to hurt one by hiting it on the head, but their hands and feet are very soft. The goblins blame the harpies for blighting the sight of the female goblins so they were only attracted to the weak and ugly males. Goblins claim they used to be the handsomest, smartest, and bravest of all the half-human races. But because of the harpy curse, in the long run only the goblin wimps were able to find wives, so there is nothing left in the goblin caves but beautiful females and ugly males.

Related to elves, gnomes and such, and of modified human stock, goblin males are ugly and mean-spirited, while the females are lovely and sweet. Goblins once ruled much of Xanth, but a spell that caused the females to prefer the worst males caused them to decline in power over the centuries, and today they exist mainly underground or in mountain warrens. Their war with the harpies almost ruined the construction of Castle Roogna.

Golem

A construction of inanimate objects animated for a purpose. Grundy the Golem is an example.

Gorgon

The personification of the promise/threat in woman. When she was young, the sight of her face stoned males; when she matured, her face stoned everyone, even animals. Sister to the Siren. Intrigued by Good Magician Humfrey, who made her face invisible so she could not accidently hurt others, she finally married him and had a son, Hugo.

Griffins

One of the classier monsters, a griffin has the head and wings of an eagle and the body of a lion. There�s hardly a better fighting animal, weight for weight, other than a dragon or an ogre. They are notoriously finicky, spending hours preening their feathers, and won�t eat anything that�s spoiled.
