[Theory] Completing the Shadows

Compared to Shadows, that were decribed as living shadows filling and inhabitating the body of the dead, Sunny is not made of only a darkness, but also a Flame. To complete his creations, he needs to give them Flame. People suggested, that the way to do it is for Sunny to give them his cores, but that doesn't really fit his Aspect. Instead, it will be through something, that was available to him this entire time, but nobody noticed. Through his domain. Unlike other Supremes, Sunny was building his domain since him being a Sleeper. This poses a question whether he could have used it in some way, even before he reached Supremacy. And I think he could, specifically to do 1 thing: create a Flame. I think his cores function as an eye and therefore a funnel of the essence storm, like the one in Shadow realm, to grind down Shades into essence. The shades he can grind down are only the ones, that are the same rank as him or bellow. He can then direct the essence to either fuel his ascention or funnel it into his Shadows giving them the Flame.
