As far as the detail that Grandfather's last walkabout was -1000 means little unless it also stated that Aslan were not on the coyns until afterwards. It's a bit difficult to think that no earlier coyns were ever found given that archaeologists 'know' they appeared around -75000. How did they figure that out if they never found older coyns?
Ishmael,
How do they know the age of coyns? How do you think archaeologists know the age of anything?
You also need to remember that coyn sets aren't found laying around. They're vitally important to Dryone culture, truly important when we realize what happens to Droyne that can't or don't caste. Discarded coyn sets aren't to be found in Droyne midden heaps and the owners of sets that aren't in Droyne hands really don't want their provenance looked into.
Droyne history as told by the Droyne?
Essentially yes, and that's a big part of the problem.
If it is stated thus and if a handful of people know the truth, it would probably be suppressed if it might have a perceived negative impact on relations or trade.
Most likely, but it's more of a public relations issue. As has been pointed out repeatedly, the upper echelons of Imperial society and government most definitely know about the
Pathfinder and know that the Major/Minor labels are nonsense on their face, they just don't want any public upheavals over those facts.
Why would the ancients meddle with 3 of the major races ( humans, droyne, and vargr ) and leave the others ( aslan, hivers, and k'kree ) alone?
Timing. Humans, Droyne, and Vargr were around when the Ancients were active. Humans and Vargr were Ancient experimental subjects and client races while the Droyne were the Ancients. The other races you list were had not developed even rudimentary civilizations yet and, in the case of the Hivers and K'Kree, were relatively distant from Ancient's stomping grounds.
Reducing any alien race to one or two stereotypical tropes is a mistake
Agreed. I'll state that the reduction of the Aslan to a trope has been done more at the hands of the Hobby and less by
GDW and other publishers. Too many GMs simply spin the Aslan as "Samurai Pizza Cats".
