I haven't used Eris much but I do use many asteroids & I use the Transneptunians. I have Eris conjunct Saturn in the twelfth house in Aries. I was left in an Ashram young (institution/yoga-cult). I fought the Ashram establishment & was exiled, later supporting people who were abused as children there. The Ashram was a big opponent to me, it was Saturnine in it's authority over me. I shattered many deep beliefs in my fury against what they had done to us kids. I was confrontational feeling I had but a brief chance to get my truth out there. I have no doubt that many people I argued with over this found me very warlike. One (lovely) swami on the right side even gave me the nickname Xena. I do have a tendency to argue with authoritative males that are older than me.
