It is already too late to undo the tampering, as the value of Orion
slaves makes itself felt on the open market. Of all the races the
Orions have known, the Rigellians will never deal in the sale of
Orion slaves. The thought of the fortune the Rigellians passed up
will always inspire deep reverential awe in the Orions [FASA].

Half the galaxy is occupied by the Danons (who may have visited Earth and
started the Devil legend). Near the center of the galaxy, they encounter
the slug-like Torgas and war breaks out which will last thousands of
years. The Danons will eventually be driven back to their homeworld where
they will construct their Great Machine as a last line of defense against
outside attack, and will worship it [ON 13].

The Senate hall on the Klingon homeworld is built [ON 1].

11,157 B.C.
A contingent of both Grey and Ruddy Orions propose the Namazz
Accord to the Kammzdast signatories. In their altered version of
this event, the name of only one Grey Orion, Dufen Maads, is
preserved and he is referred to as a Ruddy. No mention of any
other Greys is made, though they perform the bulk of the work in
planning the re-ecologizing of Botchok [FASA].

11,050 B.C.
For a few days, the Rigellians detain a Grey Orion, Talduk Sik,
part of a technical working group about to go outsystem. He is the
first Orion that the Rigellians study, and he is carefully interviewed
and questioned. This occassion, however, will become almost
mystical to the Orions, particularly the Greys. Even in the far
future some will still think of the Rigellians as their Makers.
For their part, the Rigellians will think of the occasion as the
first time they began to feel forebodings about the Orions [FASA].

space--all without starships but with an interstellar transporter.
An unspecified interstellar war chases the Nevisians back to the Nevis
system, dropping out of sight after withdrawing their ambassadors and
explorers. A thousand years later interplanetary war breaks out,
and in the millennia to come they will forget the science behind
their technology (attributing it to their Gods) even though it is fully
automated [TOS #81].

10,414 B.C.
The Greys of the Orion colony on Sharu, aided by Ruddy managers and
Green workers, divert a portion of the planet's industrial capacity
to their own purposes without being detected. The textiles,
calculators, and jewelry they produce is tiny and economically
unimportant, but it is the first time that Orions produce goods for
their own benefit on an alien world [FASA].
