I’m just thinking they probably don’t send up a message like “hey, we’re right fucking here”, so I’m left wondering are there signs to look for or do Imperial forces just have to kinda happen upon it?
My concept of a chapter was remnants of the 3rd legion loyal through the heresy though going renegade in the centuries after the Siege of Terra before settling on a planet that had either been forgotten since the heresy or just hadn’t been relocated during the Great Crusade. Mostly since then they’ve only been fighting minor threats like the occasional Ork or Drukhari raiders.
I also wanted to use some HH models for it since I really like them.
Given those circumstances, how feasible would it be to maintain a suit of Tartaros armor and a squad or two worth of Cataphractii armor into modern 40K?
