Extinction Cycle Timeline Guide
A search-friendly timeline overview connecting VX-99, Building 8, Team Ghost, the original war, Dark Age, and parallel branch chronology.
Timeline Overview
The Extinction Cycle timeline starts with the buried VX-99 and Building 8 context, moves into the first outbreak and Team Ghost's main war, then branches into reconstruction, Dark Age politics, and parallel regional survivor tracks. The canonical full-spoiler page is the timeline; this guide explains how to approach it.
Major Eras
| Era | Core pages | Notes |
|---|---|---|
| Origins | VX-99, Building 8 | Program and facility context before the wider collapse. |
| First outbreak | Extinction Horizon, Team Ghost | Main entry point for the war and its first responders. |
| Original war | Reading order | Main sequence of campaigns and consequences. |
| Later era | Dark Age | Rebuilt society and later Variant conflict. |
| Parallel branches | Survival, New Zealand, Redemption | Branch tracks with internal order and careful confidence labels. |
Timeline Confidence
The wiki distinguishes explicit dates from inferred placement. Some events are clearly ordered by book sequence or direct consequences, while others belong to a branch era without a confirmed exact relationship to every other branch. That is why the full timeline uses confidence labels instead of forcing every story into a false precision.
