Dark Matter Is Vanishing 星图绘制员 II · 暗物质正在消失
Star Map Draftsman II: Fate of the Galaxy is the free, complete sequel to Federation War. Dawn Lucius is still a Star Map Draftsman, bonded to a Star Source that lets him harness dark matter, and in Book II dark matter is vanishing. This page is series lore for readers and search, not a physics encyclopedia. Read Book I first, then Book II.
Dark matter in this hard SF series
In Star Map Draftsman, “dark matter” is a story term with hard-SF texture — not a Wikipedia physics article. Its density rises wherever a Star Map Draftsman appears, Draftsmen mark newborn stars to curb it, and Orion Arm powers scheme to control it. Readers who land here from a “dark matter” query should treat this page as fiction orientation, then go to the books.
Book II opens when that substance begins to vanish. Scientists argue. Politics accelerate. Dawn still means to protect his son Stacean. The chapters carry the plot; this lore page stays spoiler-light.
Fiction lore, not a science wiki
If you arrived from a query about “dark matter,” know this site sells no cosmology lecture. Star Map Draftsman is hard science fiction by Mango Taoist: first contact, Orion Arm federations, and a father who never stops fighting for Stacean. “Dark matter vanishing” is the Book II premise: what happens when the substance that gathers around a Draftsman begins to disappear.

What “vanishing” means in the series
In this world, dark matter is not background noise. Near a Star Map Draftsman its share climbs close to one hundred percent; across the universe, the books put it at about eighty-five percent of all matter (real-world Planck 2018 measurements give about 84%). In Book II that dark matter is vanishing. The hearings over it are not finished. The war is not finished either.
This lore page stays spoiler-light: no ending dump, no twist list. The 22 chapters of Book II carry the plot. Use this page to orient — then read.
Why read Book I first
Book II assumes you know Dawn, Stacean, the Star Source, and the three federations from Federation War (25 chapters, free and complete). Starting at “dark matter is vanishing” without Book I skips the stakes. Official order on this site and Royal Road: Earth first.
Practical path: From Earth → finish Book I → Book II chapter 1. Longer notes: How to read.
Stakes after Federation War
After Book I, Dawn still carries the Star Source. Stacean’s stakes rise again. Dawn still puts his family first. White Crystal, immortality as governance, returns. Hub-safe only here; the books hold the rest.
