Beauregard the DemonEdit
A highly intelligent demon of Xanth who is writing a doctoral thesis on the supremacy of demons over other lifeforms entitled "Fallibilities of Other Intelligent Life in Xanth". Once owed a debt to the Good Magician Humfrey after seeking information from the Good Magician on other lifeforms. He served time in a small vial for Humfrey, answering questions for people. He stayed in the vial to gain further information. Beauregard met Good Magician Humphrey in demon school, where they became friends and greeted each other with insults.
The Brain CoralEdit
A form of coral kept in stasis in preservative fluids in the land of Xanth. Its goal was to prevent the awakening of the Demon X(A/N)th, but it failed. Many people are held, or have been held, in its preservative fluids for eventual release including (Neo-)Sorceress Vadne, Magician Murphy, and Harold Harpy. The Brain Coral was a main character in the book The Source of Magic.
The wife of the demon X(A/N)th and mother of Nimbus. She lives in the Nameless Castle. Her talent is to form poison from water (more like the chlorine used to clean things with). Before she met demon X(A/N)th, she was ugly and had only one tear left in her eyes, half a tear in each, and if she was to cry that last tear, she would become blind. In the end she shed the tear when Nimby (demon X(A/N)th in disguise) was put to fire by her horrible parents. Nimby and Chlorine have a son named Nimbus.
The demon whose extended presence created Xanth's magic. He is constantly at battle with Earth, Jupiter, Neptune, and other demons who represent the planets in an astral game of gaining recognition. Earth is currently the most recognized one with Xanth coming dead last because nobody seems to believe in it. X(A/N)th is the star of the 20th Xanth book, Yon Ill Wind as Nimby, and the 23rd, Xone of Contention. He currently enjoys living in the floating castle with his consort Chlorine and son Nimbus. He has also been known to travel in the form of a horrendously ugly donkey-headed dragon called Nimby.
Also called Cumulo-Fracto-Nimbus, this demon cloud roams the land of Xanth, blowing up storms to cause mischief. Later, he tamed Happy Bottom in the Region of Air and had a daughter, Fray Cloud (Fracto and Happy Bottom). He was introduced in Centaur Aisle and appeared in many subsequent books.
The Gap DragonEdit
A dragon that lives in the Gap Chasm that runs the length of Xanth. Because the Gap Chasm had a forget spell put on it by Dor in Castle Roogna, nobody could remember it and therefore couldn't remember the dragon, making anyone who entered the Chasm easy prey. In Dragon on a Pedestal, he was de-aged at the fountain of youth, after which he was befriended by six-year-old Princess Ivy. Ivy renamed him Stanley Steamer because the Gap Dragon can only breathe steam, not fire. After an accident with Jordan The Barbarian, Stanley was sent far away. He was later found by Jordan The Barbarian, Threnody, Grundy The Golem, Rapunzel, and Snortimer at a Faun and Nymph lake retreat. The Gap Dragon still today protects the Gap Chasm from intruders, catching prey, and always being a faithful friend to Princess Ivy. He is married to Stella/Stacey Steamer (Princess Ivy named her Stacey but the Xanth lexicon put it down as Stella). They alternate guarding the Gap Chasm and watching their son Steven.
Formerly called Tropical Storm Gladys, Happy Bottom was blown into Xanth from Mundania when the Demon X(A/N)th entered the land of Xanth, stirring out magic dust and causing madness. She was tamed by Fracto later. Their daughter is Wynde Tchill.
Jenny Elf and Sammy CatEdit
Jenny is named after a fan of the Xanth series who corresponded with Piers Anthony after a severe car accident that left her partially paralyzed. Jenny, who is based on the elves of the ElfQuest series by Wendy and Richard Pini, comes from the world of Two Moons. Her constant companion is her cat Sammy, who can find anything but home. Her friends are Che Centaur and Gwendolyn Goblin. They are introduced in Isle of View. Jenny marries the werewolf Prince Jeremy in Zombie Lover. Sammy Cat, who is named for the Mundanian Jenny's pet cat, has his own adventure as a main character in Up in a Heaval, meeting his own true love Claire Voyant Cat in the process.
A 100 year old man transformed into a tree by Trent in the Xanth universe. He's rejected offers to be transformed back into a man and seems to like being a tree. Later travels with Breanna of the Black Wave (he shared a body with her during the journey). He later gets transformed back into a man and marries Breanna. They have a child named Amber Dawn.
The wisest of birds and keeper of the seeds of the tree of life. She is introduced in Dragon on a Pedestal as a leader of the winged animals of Xanth. It is said that she survived the destruction and recreation of the universe several times already. She married Chex Centaur to Chieron Centaur, and commanded all winged monsters to protect their son Che. Her chick is Sim.
Snortimer is the monster under Ivy's bed in the land of Xanth. He loves to grab at pretty young ankles. He will fade out of existence when Ivy gets too old to believe in bed monsters. He stayed with the fauns and nymphs in place of Stanley Steamer (the Gap Dragon).
