Magnus is a man from Xanth. His talent is verisimilitude. He was introduced in Jest Right as a major character.
Magnus is the husband of Jess.
Magnus is a showman. His talent let him see through Jess's curse enough to take her seriously on an intellectual level. He and Jess meet Myst and take her on their adventure, standing in loco parentis. After he fell in love with Jess, he changed his name to Nobody to work around her curse, because Nobody takes her seriously.
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.
