Magician Loudspeaker is a curse fiend man from Gateway Castle in Xanth. He was first mentioned in Demons Don't Dream.
Loudspeaker was killed in battle with Hydrogen in 408.
Loudspeaker was an Evil Curse Fiend who turned the curses on his own folk. Hydrogen defeated him, creating the Forbidden Regions in the process.

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.
