God Fearless you don't have to TELL everyone that I created the Equilibrium Faction! And yes I shouldn't be alone, there should be a second spot for someone else to be Nexus's partner.
I'll do some brief explaining then.
The Equilibrium Faction is far away from the other two, smack dab in the middle of an empty plain. (oh and I think Fearless said that the Angel world is like humans but there's clouds instead of roads and floors). History - Many years ago a black-and-white couple (Light and Darkness)gave birth to two Greywing twins (a girl and a boy) - hybrids of light and darkness, and nobody accepted them, not even their parents. They were sent away at the age of six, as the parents thought that the twins were capable of taking care of themselves. Exiled to the plains, they started to build houses, and they never went back. Soon, more and more Greywings were born (curse those parents without thinking twice! xD), and they were all sent away to the same place. The number of people grew and soon they were powerful enough to start their own faction - the Equilibrium Faction.
It's awfully low-key though, so if you ask anyone if there's a third faction, he'll probably say 'i've never heard of it'. You can learn more about Greywings in some older books though. But since they're exiled at a young age people don't really know their intentions and things...It's so far away, and so secretive. It focuses on peace and balance, and read my SU to see Nexus's personality. The faction thinks like he does. you can say it's the right way, a strange way, or a twisted way. It's up to you.
