Vormir

Vormir is a planet located in the Helgentar System, and is the sixth closest planet to its sun. A barren and desolate world, it houses rocky, mist-covered cliff, which is where the Soul Stone is located. Following his interaction with the Tesseract in 1945, Johann Shmidt, aka the Red Skull, was transported to Vormir and became the Stonekeeper. Thanos came to Vormir with his daughter, Gamora, in search of the Soul Stone. Acquiring the stone required a sacrifice however, and Thanos sacrificed Gamora.
