In classical Greek mythology Eris is the sister of Ares and the goddess of Discord the apple she has in her hand would be tossed onto a field of battle and any combatant dumb enough to look would fight to the death to possess it (It was said to made of gold)
It seems that no one has actually explained why her name is Eris. In mythology the Goddess of strife and Discord is named Eris, Greek for strife , keeper of the golden apple of discord. Within mythology it is said that Eris used the Golden apple to cause a dispute among several of the Gods leading to the Trojan war. Why do I know these things?
I do know who Eris is, what the golden apple is for and the story. I just didn't know that r63 Discord is called Eris just because somebody named her that doesn't mean her (mine) name is Eris. Fitting name though, couldn't think better anyway :3
