After enough overly curious 'Puffs were sucked into The Void's pull, they banded together to create their own little world away from the achingly bright colors of the rest of their system! Vortexity is based on more modern cities of earth, but lack the bright neons and colors of Central Star!
fashion
Voidpuffs have seen many a style when visiting earth, but their favorite by far was the more modern Gothic style, the dark on dark clothing with pops of bright reds or neon was jarring and instantly caught their interest! Spikes, chains and leather are also things they picked up over time, and their styles vary quite a bit!
culture
Vortexity is actually the most modern and futuristic place in the Galuxy, they have the power to warp space freely and can pick up whatever catches their fancy when visiting earth. Voidpuffs aren't overly concerned with rules or hierarchy, they are rather solitary by nature and each one has their own way of doing things.
The only truly unifying aspect of Vortexity's culture is their love for dark color and silence, you could go for weeks and only ever hear the ever pulsing sound of The Void around you.
music
Voidpuffs are not able to create music, nor do they wish to. However, The Void seems to have a tune of it's own always playing lowly in the backdrop of the silent city, a constant loop that never changes. THEME ♫
