Foul's Co-Dragons, the three Ravers, are just as bad. They were originally three human brothers whose evil was so great it survived past the destruction of their physical bodies as incorporeal demons with a thing for possessing people. In addition to being willing accomplices in all of Foul's crimes note Word of God says they think that when he breaks free of the Land, they can ride his metaphysical coattails into godhood themselves., and sharing his gleeful, psychotic sadism, each Raver has racked up a number of atrocities of his own. Moksha Jehannum Fleshharrower and Samadhi Sheol Satansfist both did stints as Foul's head general, massacring countless innocents—and their own troops. Individually, Samadhi, as Gibbon na'Mhoram, was the head of a Path of Inspiration that sacrificed countless lives while lying to the people of the Land that it would help reverse the After the End conditions of the Sunbane, when in fact it was just making it worse; Moksha stalked Covenant over much of the Second Chronicles infecting him with venom in order to force him to use his ring at full power whether he wanted to or not, which would have destroyed the world, which was the plan. Turiya Herem Kinslaughterer doesn't show up as often as his brothers, but commits one of the single most appalling atrocities in the Chronicles: single-handedly committing genocide of the Giants of Seareach while they refused to fight back.
Ensemble Darkhorse: Vain in the second trilogy. He does absolutely nothing, not even moving an inch, unless it's absolutely, positively required. He only speaks once at the climax. The fact he's the representative of a species which had been thought of as Always Chaotic Evil which is trying to be The Atoner doesn't hurt.
Heartwarming Moment: When creating the new Staff of Law, Linden takes a moment to help her friends.
With the Staff of Law and the white ring. Linden caressed the fatigue out of the First's limbs, restored her Giantish strength. The rupture in Pitchwife's lungs Linden effaced, healing his respiration. Then, so that she would be able to trust herself later, she unbent his spine, restructured the bones in a way that allowed him to stand straight, breathe normally.
Pitchwife's words as Linden returns to her own world, "Have I not said you were well Chosen?"
In the first book, Thomas Covenant does something horrible, which firmly establishes that, unlike a typical fantasy protagonist, he is notThe Cape. He spends the rest of the first trilogy trying, painfully, to drag himself back out of the moral black hole he fell into. Covenant's behaviour lead to a kind of cascade effect whereby the majority of bad stuff that happens in the book, and a lot of the series, is a consequence. The same goes for a significant amount of Covenant's suffering. Basically, it haunted Covenant for the rest of the series. For instance, Lena gave birth to Covenant's child, who was not completely sane, and went on to break a chunk of reality (the Law of Death) and give the Big Bad access to infinite undead armies of anything, up to and including fossils.
Foul himself has an odd crossing, because it is entirely verbal before he has a chance to actually do anything. Just reading his rant to Covenant about how he is going to corrupt and destroy the Land and there is nothing anyone can do to stop him, culminating in the declaration that he will annihilate hope from the universe, puts you off on rooting for the guy for good. It all just cements Foul's rep as what Card-Carrying Villains want to be when they grow up.
