Trentia is a woman from the Isle of Illusion in Xanth. She was mentioned in The Dastard.
Trentia is the daughter of Iris and Trent and sister of an unnamed brother, Irene, Ilene, and Trenris.
Trentia was delivered after the rejuvenation of her parents. The triplet princesses are not sure of her name. It could be Irenti.
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.
