Let’s say you’re part of a bunch of immortals who have been around since ancient times. Let’s further posit that you feed on people and are better than normal humans by any physical measure.
There was a time when there were only a few of you — the First Ones — and wherever you were at the time, you gave your species a name in the local language. That name would translate to “super-humans” or “immortals” or “silent killers in the night” or something like that. Something badass.
Unfortunately, time has passed, as it tends to do, and language has changed with it. That badass name doesn’t mean quite what it used to, either phonetically (I spent the last half-hour looking up the phonetic match for “douche” in Sanskrit and Sumerian but didn’t find anything useful), or perhaps the actual meaning has changed into something entirely different, the way “lesbian” has.
Any thoughts or ideas are welcome!
