I've been taking a look online at this Segmentum and it seems the least detailed of all. I'm aware the Macharian Crusade took place there, the Sabbat World are there, Tanith was there.

I'd appreciate any info on:
Alien races with influence there, minor races, activity of the major races.
Marine Chapters from there.
Imperial Guard from there
Notable Worlds and additional information.

thanks.

Well, many worlds rebelled against the Imperium in 999.M41.

I once seen a PDF downloadable rulebook on Bell of lost souls. it's about the Macharious Crusade. Good info on what regiments were participating. Maybe some info about the system. But keep in mind it is not official G fluff. it is fanmade, but most of it may be true.

Pacificus is maybe the 'peaceful' segmentum.?

Its small, and most known aliens seem to be 'nomadic' ( like Eldar and orks ).
Macharius should provide some background as should the sabbat-crusade.
This segment has a fleet base, Hydraphur. There seems no notable Guard regiment to be ( IG dex ) so BL's Tanith 1st and only and the other guard formations
of that sabbatine crusade may be all that is. But as said, Macharius is the key.
IG codex ( 1999, 3rd ed ? ) has Solar Macharius and his crusade on a Map on the last page.
The old dex and the actual 5th ed codex both have Hoth on a map.

Space marines have 3 home worlds there, Dark Sons and Exorcists and White consuls chapter.
Again, no conflict mentioned. ( SM dex ).
