The Transdimensional Void Runners from both the Universe of the Magisterium and the A.I.-ruled Earth in the universe of the Empire of the Solar Throne have contacted the Empire of the Itinerate Tree Dweller, a nation on a parallel Earth. The government of Emperor Erik Kersk has allied with the missionaries of the Hesychast Order but is hostile to the A.I. machines from the parallel Earth including the Empire of the Solar Throne. His government has captured three dimension-hopping machines from the A.I. enemy and is building his nation's own dimension-hopping vehicles. The Empire has already established diplomatic relations and trade with the parallel-Earth nation of the Independent National Community of St. Ives and has had contacts with other governments on St. Ives' Earth.
