The idea

In 2016 I was reading the latest book in the Horus Heresy series, struggling to work out where each group was in the galaxy. From this I had an idea to create a map that would show the passage of time and the movements of these groups.

I envisioned a timeline at the bottom of my computer screen that as you scrolled along it, events popped up with arrows that indicated movement of particular characters or groups across the galaxy to new events. Each planet, character or group was represented by a dot and hovering over these dots would give information on that location or person at that particular moment in time.

Since then the map has evolved and four years later, although it has deviated from my original idea, it is complete.

How You Can Help

If you spot something that is incorrect or needs updating, please do let me know in the comments below.

Alternatively I have a couple of Google Sheets files available for public edits where you can make suggestions.

  1. Locations – tell me if any planets are in the wrong place, or add new ones to the map
  2. Timeline – tell me if I have put an event in the wrong order, or I’ve missed someone important
