Maleldil decreeing that, once humans have been created, the Oyarsa of Earth would have to cede control of the planet to them - a concession not demanded of his colleague of Mars/Malacandra, who was left to rule over the planet's intelligent beings. The Bent One first tried to seduce the Martians, who then had the technology to build spaceships, to colonize Earth and live there as his subjects. This plan - directly contradicting Maleldil's plans for Earth - was foiled by the other Oyéresu. Thereupon, the Bent One attacked Mars and inflicted vast damage there, causing the complete extinction of its winged creatures (who might have been an additional intelligent species, birds, or both - the reference is not clear). Only with enormous effort was life on Mars preserved. This is, in effect, Lewis' version of the events known in Christian theology as The War in Heaven: 7 Then war broke out in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. 8 But he was not strong enough, and they lost their place in heaven. 9 The great dragon was hurled down—that ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him. [Revelation 12:7–10 (NIV)]. In response to his destructive acts, the Bent One suffered confinement on Earth, where he inflicted great evil. He made Earth a silent planet, cut off from the Oyéresu of other planets; thus, Earth is referred to by the name 'Thulcandra', the Silent Planet. The Bent One, or Satan, seduced Adam and Eve and caused the Original Sin in order to make humans unworthy of getting custody of the planet, as Maleldil intended. He then continues to tempt humans into evil, so as to continue their unworthiness. However, he hates the humans, whose advent was forced upon him by Maleldil, and he mistreats and tortures also the humans who submitted to him - as seen in his treatment of Professor Weston in "Perelandra" and of the N.I.C.E. directors in the end of "That Hideous Strength". Maleldil incarnated as a man on Thulcandra to save the human race. According to the Green Lady, Tinidril (Mother of Perelandra, or Venus), Thulcandra is favored among all the worlds because Maleldil came to it to become a man. Earth will remain a silent planet until the
