Sources

Here I list all the more specific lore terms used in my blog posts together with their sources and some comments why I used them and what assumptions I made: 

• Solomon Voss
  An imperial remembrancer who lived and worked during the Solar reclamation and the Great        Crusade.
  [It's very interesting how many things or people are named Voss in 40k]
  ["The Last Remembrancer", John French, (Short Story)] 
• Avellorn
  A planet in the Segmentum Solar
  [allegedly mentioned in "Codex: Chaos Space Marines (8th Edition)"]
• Voss Prime
  A forge world in the Segmentum Solar, called the Right hand of Mars
  [Page 23 in "Codex: Adeptus Mechanicus (8th Edition)"]
• Augean RT-56
  A caterpillar used during the great Crusade e.g. by Ilya Ravallion on Ullanor
  ["Brotherhood of the Storm", Chris Wraight, (Novella)] 
  [MY version auf the Augean is based on the Hägglunds Bv 206, a Swedish-designed articulated, tracked amphibious vehicle. It's so adorable!]
• Ursh
  A nation-state on Terra before Unification was achieved. 
  ["Horus Rising", Dan Abnett, (Novel)] 
• Logisticae
  The first predecessor of the Departementum Munitiorum 
  ["Brotherhood of the Storm", Chris Wraight, (Novella)] 
• Eternity Gate
  The main gate to the Inner Sanctum of the Imperial palace on Terra 
  [a.o. "The Lost and the Damned", Guy Haley, (Novel)] 
  [The gate also having a bell tower sounds quite suitable to me]
• Maximus Thane
  Legendary Imperial Fist, Chapter Master of the Fists Exemplar, the newly rebuilt Imperial Fists and later Lord Commander of the Imperium.
  [I assume him to have been the first Grandmaster of the VIIth legion since there is no name given for this position in the pre-Rogal Dorn era. The accolades of Maximus make this a justifiable conclusion for me.] 
  [a.o. "The Lost and the Damned", Guy Haley, (Novel)]  
• Asiatic dust fields
  A region of Terra during the Age of Strife and the Unification wars, said to be in constant warfare with the Yndonesian Bloc.
  [I tried to find a region on Earth that would match the name and the very brief description we have in the lore: very dry and close to south-east asia. So I decided to go for the Sichuan region in China. It's close to the Himalazians, a dry spot with extreme temperature changes and could have bordered the Yndonesian bloc. ]
  [Horus Heresy Book Three - Extermination]  
• Arkhas Fal
  Arkhas Fal was a Terran born legionnaire of the XIXth Legion. He commanded the Legion for three decades as Shade Lord.
  [Arkhas was a grim, pragmatical and sometimes outright cruel individual. Quite fitting for a former techno-barbarian]
  [Horus Heresy Book Three - Extermination] 
• Pale Nomads
  One of the unofficial names of the XIXth legion (and/or) company names in it's pre-primarch era. Another one being Ashen Claws.
  [I find it especially funny that more dark-skinned desert people becam pale after being initiated into the Legion because of Corvus' gene-seed. I also took the names given as originating from the Xeric tribal names.]
