Booom—
The long rumble reverberated in the head of every Satrean, descending upon every creature that survive, declaring the advent of a profound being.
Zessel stared blankly in the skies. The powerful Sartrean champion did not at once react, but soon understood.
It was the sound of the World Barrier being shattered by a certain powerful being.
The homeworld of the Sartreans was a geocentric world. The giant planet itself was circled by a sun and moon, with a thick layer of ether enshrouding the system. The ether belt allowed the Sartreans to build wooden airships with sails in their feudal era, the near-thousand-year accumulation of technology hence allowing the race to create a fleet out of nowhere right when they entered the Void.
World Barriers were stalwart. Even Void Behemoths had a hard time breaking, and could at most make a small hole wherein they absorbed substances or sent out their spawns or bacterium to infect the world.
