Centaur

A Centaur is a mythological creature, that is made up of the upper torso of a man and the body of a horse. They possess the strength of a horse and are always male. It is extreamly hard for a woman in labour with a Centaur, often having to be deliverered by Caesarian Section.

Solan Battle of Corinth
The Centaurs were one half of the battle at Corinth, against Xena's and Borias's army. Borias realised that Xena was overstepping the line and went up against his own army, and worked with the Centaurs to stop Xena.

The night that Xena went into labour with Solan, Borias was killed by Dagnine. Xena gave Solan away to Kaleipus, a noble and trusted Centaur. She hoped that he would grow up away from the bloodshed and the violence.

The Amazons and Forgiving Xena
Roughly ten or so years after the battle at Corinth, a warlord, Krytus, frames a Centaur, Phantes, for the death of an Amazon, Terreis. Xena and the Centaurs must call a truce in order to discover the true identity of the murderer of Terreis.

Genocide
After the 25-year sleep, the son of Ephiny, Xenan, is hunted by the son of Borias, Belach, as he believes that Xenan has kidnapped his daughter, when in fact they have fallen in love and she is heavily pregnant with his child. Ephiny talks to Gabrielle from the other side through their Amazon bond, asking foe her and Xena to assist her son in escaping from Belach.

In his attempt to find his daughter and anger for the entire Centaur race, Belach kills every Centaur in sight and puts them on the brink of extinction. Xenan is now the only surviving Centaur and must allow for his child to be born, in order to continue the Centaur race.

Xena manages to talk some sense into Belach, explaining who Borias was and what he done, causing him to call off the attack and allow Xenan and his daughter to live together.
