And so naturally, the perspective-switch which \gls{fenestra} demands can feel unclean.
But you have to understand, their world feels very different.
We created cows through early genetic manipulation of the original animal -- the auroch.
By the 13th century, aurochs became extinct.
When people travelled during this era, they would only fear other humans.
They hated wolves for stealing their food, and in some parts of the planet, a few animals had the muscle and teeth to kill a few humans here and there\ldots at least those not paying attention, but no animal has every posed a real danger to humanity on the same level as diseases, starvation, or warfare.
No city ever disappeared because of large predators eating everyone.
Humanity has wandered the earth, fearlessly, selecting the best plots of land they could to grow all the food they wished, and fence in the meat.
Disease, starvation and war don't trouble the people in \gls{fenestra} much.
They have been replaced with the basilisk, chitincrawler, and woodspy.
By the 13th century, humans hunted aurochs to extinction.
We had tamed every forest, and ate every large beast.
Now only the cows remain -- unnatural creatures, created through early genetic manipulation.
Nobody planned this genocide -- we simply hunt too well to let large animals live.
Aurochs might have survived if they had the protection of basilisks and giant arachnids.
These might seem like unlikely farmers, but they only eat the slowest of their prey, keeping their numbers `under control'.
And we might say the same for humans, despite the little land they manage to protect.
Disease, starvation and war don't trouble the people in \gls{fenestra} much, but families can swell and shrink in much the same way.
Any couple may have half a dozen children, but the population never grows beyond the land which people manage to capture.
Just as Europeans once considered the black death, and other plagues, a standard way to die, any market place in \gls{fenestra} will have updates on what ate whom recently.
This leaves that world very similar to ours on-balance, but very strange in all the details.
