What are the origins of the rings of life and void, and do they appear in all sessions?

They’re Jujus, one of their main traits is the fact their existence is dubious and cyclical. However, the Ring of Void appears to be, potentially, the Black Queen Ring from the Alpha Session, and the Ring of Life was given by Hussie of all people to Vriska, who then punched it off his hands, then Tavros took it, then John, and now it’s currently on Calliope’s hand. There’s also theories stating they’re both the same and One Ring.
