The history of the known spheres is best viewed in sections, as with the history of many other areas. This work has been divided into the following sections: The Aetaus Primus (prehistoric), The Pre-Classical Age (of the "First Migrators," the Reigar, and the Juna), the Classical Age, and the Modern Age (itself divided into sections).
Most of the events covered in this work have little or no effect on the histories of ground dwelling nations, however. The natives of groundling nations have rarely had any contact with the goings on of the worlds beyond them. There are exceptions, and space travel is part of almost every worlds history. But rarely has space travel been an important part of a world's development.
Two calendars are included. One is an abstract calendar, listing events in relation to today. The other is one of the Elven calendar, the Olven Chronicon, which is one of the few standard calendars in the known spheres. Use of this calendar is limited mainly to elves (the elves of Oerth in Greyspace being the best example), but others have adopted it as well.
For the earliest dates, historical records are unreliable, being based mainly on mythical records and artifacts. As such, they are subject to debate. They are included here because they help to put later events in context.
