Opposite themes from HK? decend vs ascend. Sun vs moon. others?

So the main Opposites I founds was the obvious Depend into hollowness vs ascend into pharloom. “Final boss” hk radiant sun vs grand mother silk looks like a moon in her cocoon. And maybe a stretch but HK has last stagway with fully destroyed eggs vs the bellbeast having kids and starting to repopulate. Havent played HK in a long time, are there others?
