In this universe there are six ancient stones, the infinity stones. Each of them infused and harnessed by six ancient goddesses spread out across the universe…
This is the Space Stone, glowing blue, and harnessing the very vacuum of this universe. Its goddess known simply as Space, lives in Asgard, in a secret tomb. She is sealed away inside a massive crystallized cube known as the Tesseract, immune to her power.
If she was unleashed, she would cause imbalance and destructive change everywhere she went. With the flick of her wrist she could change the ways the stars and planets are. She would recreate the universe in her image. The universe would suffer the wrath of an unstoppable goddess…
However, in the ancient texts, it was said that he who freed a goddess from their eternal prison, she would accept them as her love for eternity…
You were hoping to free her, so you arrive on Asgard, slip past the guards, and enter the tomb, you see the ginormous Tesseract, near impossible to open, and you hear the cold breath of an annoyed goddess inside. Years dormant inside has made Space extremely needy for her freedom and for the changes in the universe she will make.
