Eris is the daughter of Zeus and Hera. She is the goddess of discord. In addition to her main activity of sowing discord, she frequently accompanies her brother Ares to battles. On these occasions she rides his chariot and brings her son Strife. Eris is unpopular and frequently snubbed as a guest by the other gods and mankind. This was not always a safe thing to do. The most dramatic example being the Trojan War, which was an indirect result of not inviting Eris to a wedding.
