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 Soul Stone, glowing orange, and harnessing all the life force and souls in this universe. Its goddess known simply as Soul, lives on Vormir, in a secret tomb on a mountain. She is sealed away inside an ancient seal, guarded by an immortal wraith. The wraith only frees Soul if the being freeing Soul gives up the thing they love most, hurling it off the cliff as a sacrifice…
If she was unleashed, she would cause death and sorrow everywhere she went. With the flick of her wrist an entire population would fall. 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 Vormir and climb the cliff, you see the seal at the bottom of the mountain, the wraith standing nearby on said cliff, and you hear the sorrowful tears of a saddened goddess inside. Years dormant inside has made Soul extremely desperate for her freedom.
