In the first book of the Stratification series, set in an earlier time in Czerneda's Trade Pact Universe, the Clan has not yet learned how to manipulate the M'hir to travel between worlds. Instead, they are a people divided into small tribes, scattered over a fraction of their world, and prevented from advancing by two other powerful races who control both technology and terrain.
