Now to let everyone in on a little secret. My cousin and I have been secretly sharing an account over at Bolter and Chainsword, where we’re collectively known under the handle ‘Espada Azul‘. It’s a bit of an in-joke between us, with him being ‘Espada’ (as the gung-ho male) and me being ‘Azul’ (since Blue is my favorite color).
Anyway a few weeks before me and my sister left for the United States for vacation, ‘Espada Azul’ got involved in a little forum project in the Bolter and Chainsword, over in the Liber Astartes subforum (where most of the D.I.Y. or Do It Yourself Chapter backgrounds are hammered out), trying to map out the domains or homeworlds of the Chapters that were birthed from the Liber subforum… Or at least, it started that way.
This is pretty much the result of it.
Go on, click on the image to see just how BIG (and detailed) it is.
Yes, the file is massive, but it would have to be, since it has to contain most of the Astartes Homeworlds shown in the 5th Edition Codex: Space Marines, as well as many of the planets named in Games Workshop and Black Library works over the years.
While we tried to triangulate where most of the Loyalist and Renegade Chapters printed in the Librarium’s Liber Astartes section are located, some entries are just too vague (and their authors out of contact) to pinpoint, so it’s in no way complete.
Still it’s a useful tool for the folks over there at Liber to position their nascent Chapters in. Space is a massive place, and it pays to know who your neighbors are in the galactic neighborhood.

[...] Oh, and a slight segue… I updated the Liber Astartes Galaxy Star Map to add the new entries in the Librarium, as well as tweak some of the stuff that were forgotten the first time around (yes, I put Medusa in now, you can stop bugging me about it Iron Hands players) like, oh, a note on the scale. Check it out here! [...]
