Pliohippus

A potential stud, a hope for all Pliohippus horses race,
promised fulfillment for the horses' prophecy, Alas all
that vanished by treason act motivated by jealousy
and selfishness. Khail the Pliohippus has gone! My
dad! The greatest horse of all time! What about me?
Who am I?
I am just a humble foal, eager to be a member of the
hard at least. They rejected me, absurd me! Even they
Sentenced me to death, just because I look different,
Like my father, a unique Pliohippus horse supported
by new abilities!
However, life never submits, never gave up its plans;
So it burnishes the young foal Aseel, faces it with the
most dangerous conflict against the perilous beasts,
alone prepared to promote the horse kind forward to
higher-level among creatures of the earth.
