For Preteens, Teens, and Adults. 1  Tdap is a tetanus, diphtheria, and pertussis vaccine given to preteens, teens, and adults as a one-time shot, or after exposure to tetanus under some circumstances. 2  Preteens and teens 11 through 18 years old (preferably at 11-12 years old) should receive a single dose of Tdap.
Centaurs are half-human, half-horse creatures in Greek mythology. They have the body of a horse and the torso, head and arms of a man. They were considered to be the children of Ixion, king of the Lapiths, and Nephele, a cloud made in the image of Hera.
Most half-elves are the hybrid offspring of both a human and a high elf, a human and a half-elf, or of two half-elf parents (a half-elf of high elf and half-elf descent is unlikely due to high elven prejudice). They usually have a combination of physical characteristics from both sides, and can be recognized as half-elves on sight. (APG 133)
