What This Site Is
The Extinction Cycle Wiki is an independent, fan-made reference for the Extinction Cycle universe created by Nicholas Sansbury Smith, along with connected branches and anthology stories written with collaborators such as Adrian J. Smith, Walt Browning, AJ Sikes, Anthony J. Melchiorri, and others.
The goal is to be a complete and accurate guide to the books and reading order, characters, military units and factions, science and lore of the Hemorrhage Virus and Variants, and the timeline that ties every branch together.
What You Will Find Here
The site covers the main series, Dark Age, Extinction New Zealand, Extinction Survival, the Redemption Trilogy, and the Missions anthologies. It also includes character guides, group and faction pages, lore explainers, timeline pages, connection maps, and spoiler-aware reading guidance.
Articles are written as original summaries, commentary, and cross-references. The wiki does not reproduce passages from the books and does not host or link to unauthorized copies.
Who Runs This Site
The Extinction Cycle Wiki is maintained by James Graham through Capcy LLC as an independent fan reference because no single complete guide to the universe existed. James Graham oversees article maintenance, source review, and corrections. It is an unofficial project supported in part by future advertising so it can remain free to read.
