I am currently chugging my way through John French's Ahriman series about the ex-chief librarian of the Thousand Sons (it's pretty good so far, just finished the second book).

Am I correct in saying that the books so far take place around the middle of M31, many centuries after the Horus Heresy but before the First Black Crusade? Reasons for me saying this being:

• The Inquisition show up, but there is no mention of the different Ordos as far as I remember, and the Ordos only became a thing after the War of the Beast in M32.
• The Grey Knights show up and appear to be pretty widely recognised for who they are during an Inquisitorial conclave; while the Grey Knights were 'formally' created during the Second Founding, for them to be known of semi-widely within the Inquisition a lot of time must have passed.
• Iskandar Khayon is referenced by Ahriman and co numerous times, but they make no mention of his current activities and the Black Legion is never referred to.
• Furthermore, the traitor legions in general appear to be seen by parts of the Inquisition as a myth, with no real evidence for their existence; proving that they - in this case the Thousand Sons - are still a threat is a plot point. Presumably Abaddon hasn't launched a Black Crusade yet to prove that the Long War is still on.

Am I correct in my analysis?

In my effort to expand into Guard-centric stories, I wanted to look for things about the Mordian Iron Guard.

Thus far, I have found:

• Iron Guard by Mark Clapham, a full length novel
• Iron Resolve by Steve Lyons, a novella
• The Fall of Malvolion by Dan Abnett, a short story
• And apparently, the Iron Guard feature heavily in several Dawn of Fire books

Beyond this, are there any books or stories that feature the Mordians as protagonists/central characters, or is that it?

Caanok Var of Avernii seems to have been featured pretty heavily in these events, and is getting along well with Archmagos Thulia Guld in their fight against the Iron Warriors.
