YMMV / The Tapestry

• Complete Monster: Astaroth is an ancient and powerful demon (actually a "spore" created by entities called the Starving Gods) who wants the Book of Thoth so he can rule the world with it. Despite how he masks himself, he's really a demon supremacist, punishing David Menlo for summoning demons by biting his hand off. His plan for world conquest involves bringing governments around the world close to collapse before descending on Rowan with his army to seize the Book, leveraging the lives of Max's friends to get it. Upon getting it, he uses its power over truenames to expunge all post-medieval human knowledge from existence and memory, killing the vast majority of the human race. He then sets up demons as the Earth's rulers under him, instituting a vicious regime where a single person being literate mandates mass slaughter. When he loses the demons' loyalty, he loses use for them, and after consistently failing to create fully functional life, he flips out when Rowan gears up to stop him and reveals his true motives: he just wants to play God, and cares no more for demons than for humans. To this end, he attempts to summon the Starving Gods in the hopes that they will devour the universe and give him scraps to live out his fantasies with. A narcissistic psychopath caring only about his fantasies of power, Astaroth exhibits unparalleled evil even amongst demons.
