Introduced in Marvel Comics, Soul World was a beautiful, pocket dimension that existed within the Soul Stone. It originally served as a form of heaven for Adam Warlock and his friends when their souls were sucked into the Stones. His exploration of the Soul World revealed that the enemies he trapped in the Stone made new lives for themselves in this strange dimension.

As many expected, the MCU introduction of the Soul Stone in Avengers: Infinity War was accompanied by a big-screen interpretation of the Soul World. Interestingly, Marvel made big changes to what it actually is and how characters can access it.
