Five of those egg HCs.
as the White Lady's offspring, they were developed in something more like a seed pod than an egg. buncha siblings all packed together in a circle around the middle.
thanks to having the Radiance in their head, who was technically a sort of mother-nurture god, alongside just having their mind linked to tons of Infected, including, y'know, parents, they have absurd brooding instincts. they would've protected innocent eggs anyway as a Knight, sure, but where the Pure Vessel would've stood guard at most, the surviving Hollow Knight would probably hunch over a clutch with their own body.
they feared the Temple of the Black Egg before they were sealed, not for what it entailed for them or the dreamers, but because the Pale King Himself feared it. it was obvious. as the king proudly spoke of the Egg and his Pure Vessel similarly, it was the former that made him show signs of stress.
despite having a dulled sense of smell, they do not care for Rancid Eggs. they do smell enough, and are colored with Infection even after it's long gone.
they picked up enough information from the King and the King's Workshop that they could, perhaps, infuse more eggs with Void to create more surviving creatures like Vessels. in theory. they have no desire or reason to do so, of course, nor access to gods of Light. but they are capable of trying without definitely failing.
