So my headcanon Blangel successor chapter fights alongside the sisters of battle quite frequently, and has developed a bit of interfaith dialogue with them; those SOB are quite devoted to Sanguinius as well as the Emperor due to shared backstory with the chapter fighting for relics related to Sanguinius.

Reading a bit more into the lore, I now think it's more likely he's Azkaellon or a line of marines taking up the armor and name of the Sanguinor, but I'm wondering how such a position would be argued one way or the other, as it may come up in a future story I'm considering writing.

Apart from being "kind of like daemon princes of the Emperor," as I once had it explained to me, how do living saints work?

Living Saints can be many things. Some like Sabbath, Celestine, Alicia and the Companion are people of exceptionnal skill and faith who seem to display thanks to them miraculous abilities and can be transfigured by them. Super strength, speed, wings and healing abilities are rather common. They work pretty much like some sort of imperial daemon princes indeed, except their powers and transfigurating abilities can be more variable and temporary.

Living Saint is also a title granted by the Ecclesiarchy granted to particularly faithful people who did great acts of faith that can range from killing heretics, exorcising daemons to making beautiful poetry or building a lot of churches or converting populations. They are basically holy men and women, so famous and admired for their faith that they were declared Saints while still alive.

To me the Sanguinor seems to be some sort of Living Saint of the first category, but he also seem to have some point in common with the concept of Exarchs and Avatars.

Living saints like celestine get their powers from the warp, likely through some innate link as opposed to overt control (like a battle psyker), all supernatural effects in the 40k universe come from the warp in some manner or other.
