The BA's feelings about the talon and its wielder feel more interesting because they're not a blunt IF/IW or SW/TS matchup. They're specific, historically contingent and largely one-sided. The BA go berzerk at the sight of the talon (in part because of some psychic resonance thing, I think?) but it certainly doesn't seem to extend beyond that to the wider BL or to be the kind of thing that has coloured 10k years of their history.
Abaddon might screw around with them but it's not the defining grudge and it's clearly not a big deal for the wider BL. I think it's good to have a range of different relationships rather than trying to artificially make neat pairs of loyalists/traitor legions where it doesn't actually contribute much of interest.
They Described in Black Legion "impressive numbers" of the Sons Of Horus giving up the viridian green for the black and gold of the newly founded black legion. So at least some of them survived to see the legion reborn. I suspect they formed loyal stable core for the black legion to recruit outwards from (People are attracted to stable strength)
Unprecedented numbers, not impressive. Big difference. But yeah, I totally agree with you. I see the Sons of Horus as more of a solid cultural base at the heart of the Legion, given primacy by the fact that Abaddon is their Warmaster
I think this cuts to the quick of it. Khayon kind of equivocates about how much the SoH heritage really means to the BL, consciously and unconsciously, but most of it does seem to be in traditions and culture (the heart tapping thing, Cthonian terminology, topknots probably) rather than drawing from particular moments of their history or adherence to old personalities/hierarchies (see Abaddon being venerated because he's Abaddon the Warmaster, rather than because he used to be first captain).
Seeing as any feelings about Sanguinius are routed through Horus, a figure who is rejected by the legion, I can't see that as reasonably being part of SoH legacy.
