Voidsent origins

[Enkidoh]

Well, you have to remember the very term 'voidsent' means literally 'from the Void', but is usually meant to refer to something 'not of Eorzean/Hydaelyn origin' - the Void being the 'world between worlds' that has appeared in multiple FF games (specifically FFV). Gilgamesh specifically was cast into the Void at the end of FFV and became a traveller of it, using it to travel to other FF worlds (like FFVIII and XII and.. of course... here in FFXIV), so... on one hand... the term 'voidsent' could potentially mean a creature from another world.

But on the other it seems Eorzeans themselves tend to use it as a 'catch-all', placeholder term in bestiaries to refer to anything that they're unfamiliar with or has an uncertain origin, even if it ultimately has a mundane explanation (an example is the squirrel enemy the Deepvoid Deathmouse, which despite the intimidating name which literally has the word 'Void' in it.... just looks the same as any other Eorzean-born rodent.

So really, the term 'voidsent' can pretty much mean anything a person wishes something that is unfamiliar to them to be, coming from 'another world' is a good a reason as any.
