I was wondering if, apart from the Trisani, there are any other psychic breeds somewhere?
There are many races in the League universe, but the Tris and the Theians both served as a cautionary tale for all the others. The nail that stands out will find itself hammered down. As with the Naglfari and Pavakahir, a lot of the populations tend to keep a low profile as to what they can do. Self-preservation reigns supreme in a universe where people routinely kill each other for profit. But you will learn a lot more about each group as we get to them :)
