“There is a war for reality between zombies and the creatures in Avatar, and you can’t call a winner yet, because the zombies are getting stronger and faster and allying themselves with vampires, ghouls, and golems, while Avatar’s badger frigs, bearded cats, and Sotty Cooper Fritillarys are technically and generationally better motivated. The zombie advantage is that they have human roots in the rising dead of all religions. If they succeed in cross-breeding with vampires, who also have undead human roots, they will be practically unbeatable; their notorious individual weakness will be diminished and it wouldn’t take such vast numbers of them to knock over a few geeks with a talent for drawing…”
