What did the creation of our universe sound like? We now know, unequivocally, the sound of creation was a roaring, babbling, mish-mash of voices trying to talk over each other in a crowded convention center ballroom.
This was news to the scientific community, who, when notified of the discovery, voted regardless to retain the name Big Bang Theory, citing the cost of rebranding, which would be "way too high, what with all the money we sank into the TV show.”
During 2024’s Life the Universe and Everything Symposium (LTUE) we gathered the largest group ever to play the worldbuilding game Arium: Create all at the same time. Out of the collaborative work of those people came this sourcebook— a wholly new and unique sci-fi/fantasy setting designed to be used as inspiration for your own writing or gaming.
Enjoy the idea prompts in the following pages. Tag us on social media (everywhere @adepticarus) and we’ll keep an eye out for your creations based on Thesystem.
