You must be confused. How could there be more than one article named Eris? It's a disambiguation page - nice, eh?
The following is a list of links to pages that might share the same title.
Please follow one of the disambiguation links below or search to find the page you were looking for if it is not listed. If an internal link led you here, you may wish to change the link to point directly to the intended article. Or maybe you're a rat bastard intent on obfuscation. Either way is fine by us, really.
