I'd be hypocritical to tell someone "don't do that" when I've interacted with peeps that have done that enough that it has a bearing on Kell's backstory sort of. (Someone played an incubus-like miqo without understanding the FFXIV versions of succubi. There were sexy interactions. I treated it as though the Void had tainted his personal aether, when it would be more accurately explained by a portion of his personal Aether had been devoured.) However, the problem with the Void is that most people take it to mean Hell, whereas it is more akin to stuff like negative space, Lovecraft mythos, etc. The Void's purpose in our plane is to devour Aether. It may do so via several manners depending on the intelligence of the Void creature.
E.G.: The Cloud of Darkness entered a pact with Emperor Xande, granting him power in exchange for entry onto Hydaelyn. Where she'd essentially eat all the things.
Most Voidsent would rather satiate their urges immediately rather than do so, but the Cloud of Darkness is essentially the Void itself. She can play the long game, so to speak.
