From the introduction: The Archvillain Archive is a compendium of evil people. Far from monsters and creatures, these individuals represent the worst that personhood has to other. Each villain comes with a backstory designed to demonstrate their motives and history, which can easily be inserted into any game. A custom stat block is included for every villain, including Legendary—and even Mythic—actions. With Challenge Ratings spanning 15 to 30, each character included in this text is capable of being the infernal boss of a campaign! From warlords to wizards to reality-warping liches, your next Archvillain is here!
