Void is energy
Energy is everywhere, it is potential
We call it the void, not because of a lack of matter, our ships are there. No the void was in our knowledge. Our science and reason failed us, our best guesses nothing but speculation, for we could never truly comprehend, what a horrifying thing it actually was.
A Pentagram, the symbol of the five elements. Yet for Louise it was her symbol of failure. Zero successful casts of a spell, nothing but an explosion despite her exertion of will. Yet truly, the unknown being before her suggested she might be capable afterall. Or she hoped, after all what kind of familiar jumps headfirst out of a Horseshoe-shaped ship, which proceeds to blast into the sky?
For a tenno, having your ship caught in a green portal of unknown origin isn't particularly fun, not especially when you were on your way to completing a mission from Lotus. Frost however, could tell the smell of the void, yet the only one possessing it clearly was no tenno.
Frost: "Humans, how and why have you brought me here?"
Jean: "Uh, sir, you were summoned by miss Louise de la Vallière here. As a familiar, if you could take off your helmet..."
Frost: "What helmet?"
Jean (Sighs): "The one on your head."
Frost: "Oh, you meant my head!"
(Frost removes his head; everyone else screams.)
Frost: "What, never seen a Warframe before?"
Jean: "Whatever that is, I have not."
Frost: "It's basically a flesh-puppet I move by transferring my mind into it. This Warframe is called Frost and allows me to manipulate cold. Here, I'll show you!"
(Frost casts Avalanche, everyone else screams again.)
Jean: "Such powerful water magic."
Frost: "Well, duh, I'm awesome. Wait, magic?"
Louise: "Oh shit, I summoned a noble!"
Frost: "What's a noble, is it a local cuisine? I love local dishes, you always get the best stuff on moons, nothing beats low-gravity cooked foods."
(Silence.)
Louise: "Wait, if you aren't using magic, then how do you control that... puppet?"
Frost: "Void, duh."
(Everyone else faints.)
