I'm like obsessed with the Rings of Life and Void I think they are such neat concepts. They are two separate rings but they can't be narratively relevant at the same time. They can pass through dream bubbles and if you grab it in your dream, you end up holding it in real life when you wake up! Caliborn wears it in his masterpiece and uses it to be sneaky and hide his treasure and stuff. I think the wiki lists the timeline of when both rings appear in the comic? https://mspaintadventures.fandom.com/wiki/Rings_of_Life_and_Void
