YMMV / Kingpriest Trilogy

• Moral Event Horizon: Beldinas setting up mind-readers throughout his empire to make sure people can only think good thoughts. He'd been teetering on the edge for a while, but this attempt to control the very thoughts of his people is what proves that the idealistic young monk from Chosen of the Gods is truly dead, consumed by the fanatical Knight Templar. Possibly subverted in the end.
• Nightmare Fuel: Andras's situation at the end of Divine Hammer. He's directly responsible for causing the Kingpriest's assault on the Towers of High Sorcery, which results in the destruction of two of the towers and the deaths of hundreds of his fellow wizards. He ends up trapped for weeks in Fistandantilus's stripped, abandoned underground base, with no idea where he actually is and no ability to teleport out. The only food and drink he has are the noisome liquid in the base's summoning pool and the demons he summons out of it. There's a brief Hope Spot for him when The Dark One returns...but he's only there to steal his body for his next incarnation.
• Tear Jerker: Beldinas, when he does realize, though too late, what he has done, and what his actions will lead to, when Paladine himself comes to punish him, and begs him for forgiveness, but is rejected.
