E. quotDOCquot SMITHFOREWORDTwo thousand million or so years ago at the time of the Coalescence when theFirst and SecondGalaxies were passing through each other and when myriads of planets were comingintoexistence where only a handful had existed before two races of beings werealready old so oldthat each had behind it many millions of years of recorded history. Both were soold that eachhad perforce become independent of the chance formation of planets upon which tolive. Eachhad in its own way gained a measure of control over its environment theArisians by power ofmind alone the Eddorians by employing both mind and mechanism. The Arisians were indigenous to this our normal space-time continuum theyhad livedin it since the unthinkably remote time of their origin and the original Arisiawas very Earth-likein mass composition size atmosphere and climate. Thus all normal space waspermeated byArisian life-spores and thus upon all Earth-like or Tellurian planets therecame into being racesof creatures more or less resembling Arisians in the days of their racial youth.None exceptTellurians are Homo Sapiens of course few can actually be placed in GenusHomo but manymillions of planets are peopled by races distantly recognizable or belonging tothe great class ofMAN. The Eddorians on the other hand were interlopers—intruders. They were notnative toour normal space-time system but came to it from some other some alien andhorribly differentother plenum. For eons in fact they had been exploring the macrocosmic Allmoving theirplanets from continuum to continuum seeking that which at last they found—aspace and a timein which there were enough planets soon to be inhabited by intelligent life tosate even theEddorian lust for dominance. Here in our own space-time they would stay andhere supremethey would rule. The Elders of Arisia however the ablest thinkers of the race had knownand had studiedthe Eddorians for many cycles of time. Their integrated Visualization of theCosmic All showedwhat was to happen. No more than the Arisians themselves could the Eddorians beslain by anyphysical means however applied nor could the Arisians unaided kill all ofthe invaders bymental force
