SUCCESSION, IMPERIAL: After considerable study of possible alternatives, Emperor Chang decided that the Imperial succession should be based, with one modification, on the Roman Catholic method of selecting Popes. That difference was timing; rather than wait until the Sovereign died to elect a new one, thus risking a period without a ruler, the Conclave would elect a Successor as soon as the new Sovereign ascended the Throne. Acting on that, a Conclave to elect his Successor was held a month later; that was Ranger Susan Lindner, who followed his example, as has been done ever since. See below for a list of the first twenty-five Sovereigns and the dates of their reigns. Cheong Chang, 19 Jan 2128 - 1 Jan 2149 Susan M.

T T/CT: Terrene/Contra-Terrene, a more accurate term for what is often called matter/anti-matter (since both are actually matter, simply in different forms). The reaction between the two forms liberates all the energy both contain, making it by far the most efficient and least polluting energy source available. For this reason, T/CT is used almost exclusively for planetary and large-craft energy needs.
