"Okay.
I'm a species called ferryshaft, which is native to a magical island - at least an island you can only reach by magical transport - called Lidian, and which species to my knowledge hasn't ever gone anywhere else. Except literally me, I think.
I'm here because - there used to be humans on Lidian, a lot of them, and we were their primary allies there, as far as my research partner and I were able to figure from old half-eroded cave paintings and stone tablets; they taught us to read and write and lent us some of their craft, and in return we carried them on our backs, presumably faster than they could go themselves.
At some point all human-made records just stop, like they left suddenly without leaving explanation. The chances of their disappearance having been voluntary and, uh, frankly, nonfatal, don't look good, but that was a hundred and a half years ago at least and I don't know of anyone living who remembers the reason. There are other sapient species who could have been the cause. One of them, the creasia - they strike me as very capable of it." (This coldly.) "The creasia - big cats, at least half again my weight and often twice - we lost a war with them, a few generations before I was born, and their idea of a treaty was that we stand by and allow their death clutters to kill several tens of us a year, and that the adults among us keep strictly silent the arts of reading and writing, as well as anything true and meaningful about our herd's history, and in return they allow us to continue existing.
I was hoping that if ferryshaft are in fact useful to humans, then maybe whoever lived here would be interested in setting aside whatever happened to the last ones, and helping us turn into creatures that could be worthy allies to humans once again."
