There are three alignments for players in Nexus to choose from.
Kwi-Sin represents the path of death and afterlife. This is sometimes viewed as evil, but evil is not the intent of the alignment itself. Many Shaman choose Kwi-Sin as their alignment because of its connection with Shaman ideals and roleplay concepts.
Ohaeng represents the path of neutrality and balance. This neutrality can be misinterpreted as both evil and good, but neither is the intent of a follower of Ohaeng. Many Geomancers choose Ohaeng for their alignment because of its connection with Geomancer ideals and roleplay concepts. Many believe that the now-defunct Shadow subpath was the precursor to Ohaeng.
Ming-Ken represents the path of life. Ming-Ken is considered to be the "good" alignment by many players, although it is merely intended to represent life and living things. Many Poets choose Ming-Ken because it of its connection to life and healing.
