158, 190, 380 pp. Dr. Elwin Ransom, a renowned scholar, fights demonic forces with the help of heavenly messengers. The Space Trilogy recounts the adventures of Elwin Ransom (based in part upon Lewis's good friend J.R.R.

In Lewis's universe, Earth is the 'silent planet', cut off from the rest of the solar system because it is viewed as a fallen civilization.
