>A resurgence of the use of archaic heraldic devices, such as the winged reaper, took place across the 1ˢᵗ Legion in the wake of Horus’ betrayal.
Any idea what this is meant to imply? Calibanite separatists exerting influence? Coded instructions/mandates for the legion? Veterans invoking the memory of a time before there was a Warmaster, if not before the primarchs altogether, when all fealties were unquestionably to the Emperor above all?
