Timeline
Operation Burn Bright: VX-99 transforms Brett and his platoon. The first human predator form appears.
Building 8: Modern outbreak creates infected and early transformed personnel. The military loses control of the experiment.
After X9H9: Most infected die, but some survive irreversibly changed. Variants become a separate predatory threat.
Operation Liberty: Variants use tunnels, walls, and lairs. Human command learns the enemy is adaptive.
Reading Notes
Use outbreak-relative placement unless an exact date is supported by the book text. This topic is meant to explain sequence and consequence, not just order.
