Star Wars: A Galaxy Apart
The High Order
History: The High Order is an alliance of virtually every race in the galaxy with the notable exemption of humans. This is because millennia ago these species came together in revolt against humanity.
Public records from the time have been destroyed or expunged. The lack of historical documentation from this early period is generally agreed upon by the scholarly community to be the result of a concentrated efforts of the human government of the time attempting to obfuscate its atrocities from the galactic memory.
Other scholars point out that this opinion is pure supposition rooted in materials lacking context and provenance.
