From Hyperion wiki:
"A farcaster is a mean of transportation which allows one to travel immense distances instantaneously, without any time delay. They are central to the Hegemony of Man, as a system of farcasters connects the planets comprising the Hegemony's WorldWeb."

I'm starting to think about these portals between worlds, they can get different in shapes and sizes, heavily inspired by John Berkey and the huge scale sceneries from Paul Chadeisson.
I got b&w thumbnails also that I will add with other frames all together later on.
