Yes, “poik.” Listen. We actually did sit down and do some reading, mathing, and thinking about how the heck interplanetary travel worked in our setting. Some of that research was looking at how other stories have handled it to see what would be most compatible with our narrative. Some of it was looking at the actual science of space travel to see what’s reasonable for the tech level of the comic. And when we were done, it was clear that of all the sound effects humankind has conceived, “poik” was the most accurate and appropriate sound to use to denote a ship undergoing a jumpgate-powered near-lightspeed acceleration.

“Vwum” we just made up.
