This is Chex cantaur and her colt, Che. Chex's sire and Dam(that is what a centaur in Xanth calls their mother and father) is Xap Hippogryph(Sire) and i think her Dam is Cherie centaur. Either that or Cherie is her Grand Dam. Che is Baby Sim's tutor(Once her grows older) and is protected by all winged creatures in Xanth, ordered by the Great Simurgh. Another charater in the Xanth series.
