Earth is a major demon from the Solar System in the Milky Way Galaxy. He was first mentioned in The Source of Magic.
Earth is the husband of Gaia.
Earth has the ambiance of Gravity. It was introduced as a shemale, but it shows mostly a male aspect. In Xanthʼs opinion, she is rather Mundanish. He was tricked and captured by Fornax. He was hosted by Justin and was assigned the emotion of hope by the Swell Foop. He shares rule of Earth, the world, with Demon Gaia. His name is stylized as E<A/R>th.

Human men and women will not have a species in their entries. Also, if the surname of the character is the character's species, it was dropped.
If the character is a child, it will be in the description. The child will more than likely be an adult by this time in the Xanth series.
Many species are single gender, so their entries will not mention it. The species are Fury, Muse, basilisk, cenmaid, cenmare, cockatrice, dryad, maenad, sand witch, sandman, and woodwife. Harpies and nymphs are usually female, and fauns are usually male; but there have been a few exceptions that are noted.
In some instances, I have made educated guesses on gender, species, and some birth years.
